Wake-up Call: As Monarch Butterfly Numbers Plummet, will their Migration become Extinct?

More alarming news from the Monarch butterfly roosting sites in Michoacán last week: the 2013 season will surpass 2012 as the all time worst year for Monarch butterflies since records have been kept.

Ever since 1994, scientists have measured the hectares occupied by the migrating insects in the high altitude forests west of Mexico City to get an idea of their numbers.  That information typically works as a key indicator on the state of the union of Monarch butterflies and other pollinators, which fertilize 70% of the world’s flowering plants and two-thirds of the world’s food crops.

For the 2013 season, the entire migrating Monarch butterfly population occupies only .67 hectares.  That’s 1.65 acres, 72,000 square feet–or about 35 million butterflies, down from highs of 450 million in years’ past.  Think about it:  the entire population of migratory Monarch butterflies could easily fit into the average Walmart store, with 30,000 square feet to spare.

Headlines trumpeted the end of the migration.

“Monarch butterflies drop, migration may disappear,” the Washington Post reported.  On January 29, NBC Nightly News anchor Bryan Williams told viewers–incorrectly–that the head of the World Wildlife Fund in Mexico said the Monarch butterfly is in serious risk of disappearing.  In fact, it’s the migration that’s endangered, NOT the butterflies.  Important point.

The New York Times put the dismal news in proper perspective:  ”The migrating population has become so small—perhaps 35 million, experts guess—that the prospects of its rebounding to levels seen even five years ago are diminishing. At worst, scientists said, a migration widely called one of the world’s great natural spectacles is in danger of effectively vanishing.”

The news cast a pall over Monarch watchers and other nature lovers.

“My whole day got grayer,” said David Braun, an attorney, naturalist, and founder of Braun & Gresham, a law firm that specializes in environmental and land management issues in Dripping Springs, Texas.

Like me, Braun lives in the Texas Funnel, the primary flyway through which all migrating Monarchs must pass  in the fall on their way to Mexico.  He has accompanied me over the years on Monarch tagging outings along the Llano River and led ecotravelers to the roosting spots in Michoacán for Victor Emanual Tours back in the 1980s.  He was the first person to spark my imagination about how truly awesome it would be to witness the spectacle of hundreds of millions of butterflies unleashed in a mountain forest.

Catalina Trail, then known as Cathy Aguado, was the woman on the cover of National Geographic in 1976

“I remember clearly my excitement when the National Geographic story came out in 1976 announcing the discovery of the wintering grounds,” Braun wrote via email.  ”I also remember my first trip there, the magic of walking through the hushed, cathedral-like fir forest and hearing the sound of millions of Monarch wings flapping.  Today, I have to wonder if that entire awe-inspiring, glorious natural wonder will disappear in my lifetime.  It makes my short life seem even more insignificant if the great cycles of nature aren’t timeless.”

Thousands of others echoed those sentiments via social media, in comments on dozens of news articles, and in emails, on listservs and conversations near and far.  For a sampling of angst, see the Monarch Watch Facebook page comments.

“What’s happening to Monarchs is probably happening to lots of species,” Dr. Karen Oberhauser, a professor at the University of Minnesota and founder of the Monarch Larvae Monitoring Project, told the Washington Post. “This is a species, unlike most other insects, that we can count and look at what we’ve done to it. So this really should serve as a wake-up call.”

Dr. Chip Taylor, founder of Monarch Watch, which oversees the citizen scientist tagging program in which I participate,  reinforced the connection to other pollinators on the public radio program Here and Now.

In a comprehensive interview with WBUR, Taylor underscored the idea that this extreme and rapid decline is not just about Monarchs.  ”Monarchs are simply a flagship species for everything else that’s happening out there,” he said.

Taylor noted that Monarchs live in marginal habitats that support most of our pollinators– in roadside wildflower patches, between rows of cultivated crops and in native wildflower prairies.  These spaces are too often decimated by habitat loss.  Read his compelling explanation of the decline on the Monarch Watch Population Status Report.

“Those marginal habitats support a lot of small mammals and ground-nesting birds, and if we lose the monarchs, it means we’re going to lose all those things,”  Dr. Taylor said. “People perhaps do not grasp…that it’s the pollinators that keep everything knitted together out there….there’s a fabric of life out there that maintains these ecosystems, and it’s the pollinators that are critical.”

First of Season Monarchs Spotted on Llano River–Another “Worst Year” for Migration?

Two FOS (First of Season) Monarch butterflies made an appearance on the Llano River this weekend–pretty early for migrants.  They looked to be in good shape and were heading south.

We generally don’t start seeing Monarchs until Labor Day weekend, three weeks from now.  These early arrivals are called the “premigration migration” and typically show up about a month before the “real migration.”  If this is the case, we’ll be seeing pulses of Monarchs by mid September.

Recent years have been tough on Monarch butterflies.  Climate change and drought have messed with their host and nectar plants’ life cycles and genetically modified crops have sterilized their breeding grounds in the Midwest.  Wildfires and aerial pesticide spraying wreaked havoc with their journey through North Texas last Fall, and logging threatened their roosting sites in Mexico upon their arrival.

Could it get any worse?

Probably.  Last year, their population dropped to its lowest level in history.  They occupied less than three acres of the ancient Oyamel forest in Michoacán, Mexico, where they roost each winter.    That’s right: the entire migratory population of Monarch butterflies occupied a space smaller than most shopping malls.

Scientists, enthusiasts and butterfly watchers have been bemoaning the lack of Monarch butterflies on various listservs all year.  The Spring season was skimpy, and Fall doesn’t look any better.

“One of my monarch students, a 15-year-old budding biologist told me tonight that he’s seen NO sign of eggs nor larvae on hundreds of plants. He lives in a rural area; milkweed is abundant on roadsides, fields and his garden.”

                     –Debbie Jackson, Davisburg, MI, August 5

“There weren’t many Monarchs in Canada and the mid-west. I’ve been reading the butterfly counts that Don Davis has posted. Most listed zero Monarchs.”

                             –Mona Miller, Herndon, VA, July 20

 ”Where are the Monarch butterflies?” asked the headline on a MSN News story August 7. “Michigan is missing its monarch butterflies. So are Delaware, Minnesota and Montreal,” it continued.  ”We go out and are looking, looking, inspecting thoroughly,” Holli Ward, executive director of the Michigan Butterflies Project near Grand Rapids, told the Detroit Free Press….We have not seen a single egg or caterpillar.”

Monarch butterflies hit record lows nationwide,” read the headline of the Rockford Register Star in Illinois on July 26.

Our friend and founder of Monarch Watch Dr. Chip Taylor told the publication that the population crash can be attributed to weird weather in 2012, including one of the hottest, driest summers in decades. “The heat shortened the lifespan and lessened the egg-laying capacity of female monarchs,” Dr. Taylor explained.

I’m predicting a new worst year in history.

Our drought marches on, dropping water tables, shrinking our rivers and the riparian systems that sustain them and no end seems in sight.  Cocoa, my loyal butterflying assistant pictured above, could just about walk across the Llano River this weekend without getting her feet wet.  This is a first and doesn’t bode well for sustaining the milkweed host and nectar sources Monarchs need to get to Mexico.

We did have some well-timed rains this month, however.   The rain gauge showed a stout 3.5 inches.  Blooming Goldenrod awaited ubiquitous Sulphurs and Swallowtails as occasional Queens mingled with the two solo Monarchs referenced earlier.  Scattered showers are predicted for next week, which may keep the blooms in shape until our first wave of migrants typically show up–around Labor Day.

Swamp milkweed, Asclepias incarnata, a Monarch host plant, also began its late summer bloom, in smaller stands and scrawnier than usual, but present nonetheless.  We found four eggs which could be either Queens or Monarchs.  We’ll keep you posted.

Faded FOS Monarch Butterfly Lays Eggs in San Antonio Despite Dreary Population Reports

My first day of earnest butterfly gardening of 2013 met with a sweet surprise:  my FOS (First of Season) Monarch butterfly, Sunday, March 17.

And, it was a faded female, fluttering in my mulched front yard garden, lighting from one Tropical milkweed plant to another.  In her wake, about a dozen creamy, white Monarch eggs were deposited on the undersides of select leaves.  I retrieved a handful for safekeeping inside.

The sight was especially reassuring given that we just endured the worst news in history on Monarch butterfly numbers this week.   The official report from the World Wildlife Fund preserves in Michoacan, Mexico, confirmed what many of us had suspected for 2012.

The migrating butterflies occupied a mere 2.93 acres (1.19 hectares) of Oyamel forest in Mexico, the smallest recorded population in history. The number represents a 59% drop,  down from 7.14 acres (2.89 hectares) last year and the lowest population since record keeping began 20 years ago.  During the 1990s, the amount of forest typically occupied by Monarch butterflies averaged more than 20 acres.

Why is anyone surprised?  Climate change, drought, wildfires, illegal logging in Mexico, and pervasive pesticides have brewed a perfect storm that threatens the continuation of the magnificent Monarch  migration. Genetically modified crops leave our heartland void of milkweed, the Monarch host plant, starving the migrants of the only food that feeds their caterpillars.

Passage: the Decline of Monarch butterflies via CBS news.

Our friend Dr. Lincoln Brower co-authored an op-ed piece with Homer Aridjis, a Mexican author and former ambassador, for the New York Times headlined:  ”The Winter of the Monarch.”  ”Today the winter monarch colonies, which are found west of Mexico City, in an area of about 60 miles by 60 miles, are a pitiful remnant of their former splendor,” wrote Brower, who has been studying Monarchs for decades.

Scientists see ominous decline in Mexico’s Monarch butterflies,” read the headline topping an AP story that ran on NBC news’ webpage and many other news sites.   The listservs and Facebook exploded with angst from butterfly fans.

“Bad omen: More than half of the monarch butterflies in Mexico have gone missing,”  tweeted Steve Silberman, as scores of others chimed in to express their dismay.  The Monarch Watch Facebook page posted the news and dozens of comments resulted.   “Terrible news” and “So sad” typified responses, along with myriad calls to plant more milkweed.

“All in all, it was not a good year for monarchs,” said Dr. Chip Taylor, founder of Monarch Watch, in his response to the report.

Yet…thinning my thick patch of Cowpen daisies to make more room for milkweed, I couldn’t help but marvel at the tenacity required for this small, slight creature to have traveled so far to complete her life cycle.   More than 850 miles. Faded, fluttering, she sought just a few good leaves for her babies.   She didn’t give up.

And we shouldn’t either.

Persnickety Texas Milkweeds “May not Lend Themselves to Mass Seed Production”

Native American Seed Company is on a mission to restore the earth, one native seed at a time.

The 300-acre spread about 115 miles west of San Antonio on the banks of the Llano River just northeast of Junction, Texas, boasts 75 acres of native plants in production

for the distinct purpose of harvesting native seed.

The company’s nondescript cedar post gate opens onto a caliche drive that winds through classic Hill Country mesquite, agarita and sotol, then spills into planted rows of huisache daisy, standing cypress, gayfeather, American blanketflower and other native wildflowers and grasses.   Water pumped from the nearby Llano River maintains the verdant fields, and allows the company to grow, harvest, process, package and ship more than 170 species of native seed and 30 seed mixes nationwide.

Among the seed stock, two native Texas milkweeds, Asclepias asperula, commonly known as Antelope horns, and Asclepias viridis, often called Green milkweed, have challenged the 25-year-old seed company’s experts.  The Monarch butterfly host plants are essential to the Monarch butterfly migration, which funnels south through the Texas Hill Country each fall.  Native milkweeds are famously difficult to propagate, even for professionals. “Species in Texas may not lend themselves to mass seed production,” said George Cates, chief “seed wrangler” at Native American Seed.

Native Texas milkweeds require stratification–cold and moisture to soften up their outer shells.   They need 45 days of moist conditions, specific soil conditions, and alternate wet and dry periods.   Worst thing you can do: overwater them.  (Check out Native American Seed’s Milkweed Stratification process at this post.)

Gardeners and butterfly fans committed in theory to propagating and planting native milkweeds (and I consider myself among them) have been vexed in practice by their persnickety ways.   That’s what often drives us to plant Tropical Milkweed, the nonnative Asclepias curassavica that is easy-to-grow, widely available and the favorite of Monarch butterflies for hosting and other butterflies for nectar. While the practice bothers some scientists and native plant purists, our rationale is that Monarch caterpillars need to eat.   In short, it’s better to provide SOME host plant for migrating Monarchs than NONE as they pass through Texas.

George Cates

Native American Seed and the Portland-based Xerces Society, a nonprofit organization devoted to protecting invertebrates and their habitats, hope to change all that.

In 2010, the Xerces Society approached the 18-person staff of the Native American Seed Company about establishing a partnership to restore native milkweeds to the American landscape.  Xerces had recieved a $117,000 conservation innovation grant from the USDA’s National Resources Conservation Service.   “We call it the ‘milkweed CIG,’” said Brianna Borders, project manager for the undertaking, since renamed Project Milkweed.  A requirement of the grant was that the recipients match the sum by raising an equal amount.

Project Milkweed identified several U.S. regions for milkweed seed production–California, the Great Basin, Arizona, New Mexico, Florida, and Texas. “Texas was a clear choice, arguably the most important state to the Monarch migration,” said Borders.  The $334,000 was pretty much divied up equally between the areas, she said.

xerceslogo

Native American Seed was an ideal candidate for the project, said Borders, because of the company’s long involvement in native seed production and its opportune location on the Monarch flyway.  Founder Bill Nieman, a high school dropout who turned a trash hauling business into a successful landscaping and design firm and then into Native American Seed, has a long history as a conservationist. The company’s mission aligned perfectly with the task.

The company’s 100-page catalogue practically serves as a free native plant guide. The vivid and abundant photography, renderings of how seeds look when they sprout, and descriptive verbiage describing each plant’s soil type, sunlight needs, and other traits

offer a broad overview of the life cycle of many plants native to the U.S.   Especially entertaining is Nieman’s annual introductory letter in which he tackles topical environmental issues–from invasive plants and water waste to wind power lines.

Results for the Mlikweed Project have been mixed so far.  The program launched just as Texas entered the ongoing historic drought.  In April 2011, the milkweeds didn’t flower or produce seed (which is expected, given they are perennials).  Borders said the first seed harvest last year (2012) was “pretty modest.”The 2,400 linear feet of native milkweeds  produced 1.5 pounds of seed, which, at an average of 65,000 seeds per pound, amounts to almost 100,000 seeds.  Of those 100,000 seeds, 95% have been restratified and replanted.

“We didn’t set a target for how much seed has been produced because there are so many unknowns,” said Borders.

Meanwhile, others have tackled the daunting task of producing milkweed plugs.  Monarch Watch, based at the University of Kansas at Lawrence, launched a “Bring Back the Monarchs” milkweed restoration campaign back in 2010.  Last fall, the program got a second life here in Texas when it partnered with the Native Plant Society to recruit volunteers to gather native seed, then mail them to Kansas for cultivation there.

bring-back-the-monarchs

The milkweed restoration campaign previously used a Texas grower. Pat McNeal, of McNeal Growers in Manchaca, Texas, assumed those duties in 2012,  but said recently that Monarch Watch “had better success in Kansas where they have four real seasons.”

McNeal suggested that the best way to propagate Texas native milkweeds would be to cultivate the tubers for two years, then plant those in the fall.   “These milkweeds don’t adapt their schedules for us,” he said, adding that Texas native milkweeds don’t do well in containers.  The plants can have a two-meter long tap root making them difficult to transplant.  ”It’s like trying to grow a potato in a pot,” said McNeal.

Dr. Chip Taylor, who oversees the program, continued cultivation this year with a Kansas grower.  He said he anticipates that 25,000 native milkweed plugs will have been produced this spring.  All have been sold on preorder. Monarch Watch will soon set up  a “Milkweed Market” for retailers on its website so people can connect with growers in their area.

At Native American Seed, the battle for Texas native milkweed seed plods on.  Cates assumes primary responsibility for their production.   He joined the company in 2003 as a student intern in ecological sciences at Austin College in Sherman, Texas.  After graduating he came on fulltime in 2007.

On a windy Friday afternoon in April, Cates pointed to the dry landscape.  ”The grass hasn’t been green since 2010,” he said. With the Llano River flowing at an historic low, Cates mentioned the seed company will once again use its entire irrigation allotment, strategically watering wildflowers and native grasses, supplementing with a recently installed rainwater collection system.

A dry winter coupled with early, hot tempertures, watering restrictions on the Llano, and an unpredictable climate suggest months of hard work and frustration ahead for Cates.  But the difficulties haven’t dampened his zeal for restoring native plants with seeds.  ”A plant in the ground will produce 100x more seed than tubers,”  he said.  ”That’s where we’re at–we’re trying to grow a substantial amount of this seed material.”

Cates has little patience for Tropical milkweed, the easy answer for gardeners in the long haul of native plant restoration. “We’re all about having it right now,” said Cates.  “These kinds of conservation efforts can’t be done ‘right now.’  It takes time.”

“Every time you vote for Tropical milkweed with your dollar, you vote against this,” he said, pointing to tidy, dry rows of future Antelope horns, which had yet to sprout this year.

Cates kneeled down and dug his fingers into the soil to find root stock from the 2012 milkweed crop. “Half of what we do fails, but that doesn’t make us stop.”

Tropical Milkweed: To Plant it or Not, it’s Not a Simple Question

Dara Satterfield SM

Graduate student Dara Satterfield came to town in late January for the second time in 12 months to take the pulse of the Monarch butterfly population at the San Antonio River Museum Reach Milkweed Patch.  There, dozens of Tropical milkweed plants play year round host to Monarch butterflies.   Satterfield works closely with local volunteers like Mary Kennedy and Mobi Warren of the Monarch Larvae Monitoring Project (MLMP), a citizen scientist program, to monitor milkweed patches far and wide for egg, caterpillar, chrysalis and butterfly action that might shed light on the state of the Monarch butterfly migration.

Monarch on Tropical Milkweed

Satterfield, like other scientists, believes the increased availability of  Asclepias curassavica, commonly known as Tropical milkweed, coupled with our warmer winters, may have an unhealthy impact on Monarch butterflies and their migration.   The science is undetermined on that question.

A native of  Marietta, Georgia, Satterfield attends the University of Georgia where she is a PhD candidate whose dissertation focuses on the relationship between migration and infectious disease in wildlife.  Monarchs are her species focus.  Satterfield works closely with Monarch scientist Dr. Sonia Altizer, the foremost expert in the country on Ophryocystis elektroscirrha, or OE. The unpronouceable protozoan disease infects Monarchs and other milkweed feeders, often resulting in butterfly crippling or death.

Dara Satterfield

As winters get warmer, Asclepias curassavica, the only milkweed species commercially available, is less likely to die back in winter. Some scientists hypothesize that A. curassavica entices Monarchs to forego migration and winter in the U.S. This could create an unhealthy hotbed of lingering OE spores for caterpillars and butterflies that remain in the local area.   Since the spores transfer from creature to creature via physical contact with each other or the plants on which they rest or eat, scientists worry that local OE-infested Monarchs will infect and breed with populations that are passing through, possibly jeopardizing the migration.

The situation exacerbates an already serious decline in the Monarch migration.  Drought, genetically modified crops, late summer wildfires, and generally inhospitable conditions pose multiple threats to Monarchs and their migration.   It’s likely that 2012 will be the worst year, numbers wise, in Monarch butterfly migration history since records have been kept.

“Monarchs are famous for this migration so when we see what appears to be a break in their migratory pattern, we want to know why and what the implications are,” said Satterfield.

OE Spores with Monarch Butterfly Scales

But butterfly breeders and enthusiasts argue that OE is like staphylococcus–present in the general population and becoming a threat only under stressed circumstances. Organizations like the International Butterfly Breeders Association promote best practices for limiting OE in captive environments through education of its membership and seminars on managing and limiting its presence.  And yet others believe that OE is simply a part of the evolutionary cycle, killing those butterflies less fit than others.

For butterfly hobbyists and gardeners, the “curassavica question” presents a quandary:  should we be planting Tropical milkweed or not?

“This is a very sensitive subject in the Monarch world,”  said Satterfield.   “We just don’t have the data right now.” It will take three or four more years to complete Satterfield’s research.   She advises that natives are always better–which is true, IF you can find them and meet their persnickety growing needs.   Organizations like Monarch Watch and the Xerces Society‘s have launched milkweed restoration campaigns, but wide availability of native stock is still a dream.

If you DO plant curassavica, many scientists suggest cutting it to the ground in winter–unless yours is a research site like the Milkweed Patch on the San Antonio River Museum Reach.  Scientists encouraged the City of San Antonio and San Antonio River Authority to leave our milkweed patch alone as an experiment.   Interestingly, the San Antonio patch brags a lower incidence of OE (15%) than in other monitoring sites observed (47%) by the Monarch Larvae Monitoring Project.   The 47% figure is SIX TIMES the rate of OE in Monarchs that migrate to Mexico.

Satterfield suggested that a deluge of milkweed beetles at the Patch this winter decimated not only the foliage, but OE spores.  The hungry orange-and-black bugs pruned much of the diseased growth, creating a better balance for the butterflies. Apparently Mother Nature has her own way of managing the OE problem.

Milkweed beetles have defoliated the Milkweed Patch. But aren't they cute?

Mother Nature on the case: Milkweed beetles defoliated the Milkweed Patch last spring, cleaning out OE spores in the process. Photo by Monika Maeckle

“This may have removed any OE spores on the milkweed plants, which probably helped to keep the prevalence of OE low this year,” said Satterfield. She added that since our Milkweed Patch is further inland and enjoys cooler temperatures than coastal situations in Houston and Florida, the Monarch population was lower and perhaps more hearty.

In the meantime, gardeners are left to make their own calls.   Is it better to have a questionable milkweed source in your yard to provide Monarchs with nectar and host plant, or not?  

Let’s see: Tropical milkweed is easy to grow, widely available, prolific bloomer, favorite host plant for Monarchs and a great nectar source for all butterflies.   I know where I come down on that.   You’ll see Tropical milkweed in my yard.   But I’ll be sure to keep it out of wildscapes and ranch situations, and slash it to the ground in the winter.

I continue to be perplexed why this post consistently ranks as one of the most read in Texas Butterfly Ranch history.  Perhaps referencing the conservative Discovery Institute is what continues to provoke readers. Hmm.

Milkweed Guide:  Choose Best Plants for Monarch Butterflies

This plant guide for Texas milkweeds has been a perpetual most-viewed post since it was published in November of 2010.   Time for us to update it, which we hope to do soon.

“Flight of the Butterflies” in 3D a Special Holiday Treat for Kids, Seniors and all of us in Between

The new 3D IMAX film, “Flight of the Butterflies,” made the perfect Thanksgiving Day preface to a nontraditional dinner for my parents, Hilde and John Maeckle, 80 and 91 years young, respectively, and affectionately known as “Oma” and “Opa.”

Apart from the fantastic story and stunning effects, the sound was loud enough for my hard-of-hearing dad to enjoy the soothing rhythm of millions of butterflies’ wings beating.    The three-dimensional cinematography so captured his imagination that he, like the rest of us, couldn’t resist reaching into the darkness in attempts to touch the butterflies as they seemingly flit before our eyes.

This familiar story, well-told, never gets old–even to a butterfly evangelist well-versed in Monarch butterfly natural history.  Only one scene gave me pause, making me wonder if the filmmakers had taken their cinematic license too far.

The film weaves the compelling narrative of Dr. Fred Urquhart and his wife Norah, who studied the Monarchs for 40 years and are credited with piecing together the mystery of their migration. Their tenacious efforts included the development of the first citizen scientist tagging programs.   The climax of the story occurs when the Urquharts finally visit the ancestral roosts in early 1976, after Mexican national Catalina Trail and her husband Ken Brugger lead them to the mountaintop in Michoacan province near Angangueo where the butterflies wait out the winter each year.

The film depicts the elderly couple huffing up a challenging trail, seemingly gasping for air in the thin mountain air.  Upon first sight of  the forest filled with  Monarch butterflies, Dr. Urquhart appears teary.

In his first person account in National Geographic Magazine in August of 1976, Urquhart mentions the possibility that he might perish before seeing the subject of his life’s work.   Here’s what he wrote:

“Norah and I are no longer young.   At 10,000 feet, as we walked along the mountain crest, our hearts pounded and our feet felt leaden.

The rather macabre thought occurred to me:  Suppose the strain proved too much?  It would be the ultimate irony to have come this far and then never witness what we’d waited so long to see!”

But Urquhart and Norah lived to see the Monarchs and tell the tale. In the movie, he sits down in a field to absorb the magnificence of millions and millions of butterflies–floating, flitting, fleeing the ancient Oyamel trees as the sun warms them for a midday flight.  He looks down to see a tagged butterfly near his feet–thus proving that these butterflies migrated from the United States.

Watching this scene, I couldn’t believe it happened like that.   Did it?

“They couldn’t film what really happened.”  said Dr. Chip Taylor, founder of Monarch Watch at the University of Kansas at Lawrence and a longtime Monarch butterfly scholar.  ”A lot of people questioned that scene.”  Taylor relayed the real story, an Isaac Newton moment.

“What really happened, he was sitting by a tree, and a branch fell down,” Taylor said by phone.   “And one of the butterflies on the branch had the tag on it.”   Taylor said the filmmakers couldn’t replicate the situation exactly without harming the butterflies.  Deliberately breaking a branch off the tree in the protected sanctuaries where the scene was shot would have been illegal.  The tag was applied in Chaska, Minnesota.

Catalina Trail, the only living member of the team that discovered the Monarch roosting spots in Michoacan and who was present at that moment, confirmed the story.  ”That’s how it happened,” she said by phone from Austin.

As difficult as it is to grasp, branches often break from the weight of millions of butterflies.   “It happens all the time,”  said Taylor.  Each butterfly weighs half a gram. That means 907 butterflies weigh one pound.  And a million butterflies weigh 1,102 pounds.   The roosting spots can host half a billion butterflies.   Do the math.

“It just blows me away,” said Taylor, recalling a trip to the Monarch sanctuaries and an inch-and-a-half round sapling, 20 feet tall, with a sprig of foliage on the branch.  ”It would literally fold over double from the weight of the butterflies.”  And when they flew off, the branch would spring back to an erect posture, he said.

Urquhart described the moment on page 173 of the August 1976 edition of National Geographic:   “”While we stared in wonder, a pine branch three inches thick broke under its burden of languid butterflies and crashed to earth…..There, to my amazement, was one bearing a white tag!”

The IMAX movie, Flight of the Butterflies, was released last week, and chronicles the "discovery" of the Monarch butterfly roosting spot.

Some have suggested that the movie misses a chance to make a strong case for conservation.  But one could also argue that that’s a different movie. The film does much more than any other single piece of media to raise awareness of the magic of the  Monarch butterfly migration.    Once people feel the magic, then doing something constructive to help often follows–like planting milkweed.

Flight of the Butterflies, a spectacular 44-minute show, simultaneously suits children, seniors and all of us in between.   The film continues in San Antonio at the Rivercenter IMAX theater and opens at Austin’s Bob Bullock IMAX Theater in January.

Winds from the South Stall Migrating Monarch Butterflies on the Llano River in the Texas Hill Country

Hundreds of Monarch butterflies were stuck in a holding pattern this weekend along the Llano River as 20-mile-per-hour wind gusts postponed their journey south.  We observed several small roosts and many clusters.   All were holding tight to pecan tree branches or seeking refuge in the low persimmon trees hugging the Llano’s limestone cliff embankments when not battling the winds in their attempt to move south.

Paddling my kayak into the wind made me even more sympathetic than usual to their travails.    It sure helps if the wind is on your side, and this weekend it wasn’t.

My husband Bob Rivard and I tagged more than 130 Monarchs in 24 hours. The insects’ orange-and-black coloring made them perfectly camouflaged in the autumn colors of the pecan tree leaves–even more so in dappled afternoon light.

Bob Rivard Tags Monarch Butterflies on the Llano

Bob Rivard tags Monarch butterflies on the Llano. Bob won the Big Swoop contest this weekend with 12 in one net.

While Monarch butterflies were ubiquitous, their numbers appeared drastically reduced compared to years past.

How to tell?   Usually, we see clusters of hundreds.  This year it was clusters of 10s and 20s. Usually, we can snag 20 or more in one lucky swoop of the net.  This year, the record (hat’s off to Bob), was 12.

Monarch butterflies hold onto a pecan tree branch

A common pose on the Llano this weekend: Monarch butterflies hang on tight to a pecan tree as winds from the South stall their migration.

Of the hundreds we saw this weekend, only one Monarch butterfly was spotted nectaring. Usually dozens of Monarchs break from their flight in the late afternoons and evenings to fuel up on abundant Frostweed or Goldenrod.   Not this year.  The insects seemed hell-bent on moving south.

Trolling up and down the banks of our stretch of river, we spotted the tenacious flyers fighting the wind, pushing into its gales, only to be forced back with a wind gust and advancing only a few yards south at a time. As Sunday afternoon rolled around, we found ourselves netting Monarchs tagged on Saturday, thus making the case that their efforts to move south were stymied.

Jenny Singleton and Friends Tag Monarch butterflies in Menard

Our weekend resembled that of Jenny Singleton, a fellow Monarch butterfly fan who had a similar experience one week prior only  30 miles northwest of us in Menard.  ”We tagged 450 over three days last weekend (Oct 11-13),”  Singleton wrote in an email to the DPLEX list, a list-serve that reaches hundreds of Monarch butterfly enthusiasts and scientists . “There was a strong SW wind all week which kept the little guys in the trees for four days and made it easy for us to observe and tag.”

Cocoa patrols the "Monarch Spot"

Cocoa Rivard patrols the riverbank we call “The Monarch Spot,” a favorite resting and roosting area for migrating Monarch butterflies on the Llano River.

Singleton relayed that at another nearby ranch, along a spring-fed creek, a team tagged 125 Monarchs in an hour in the middle of the day. “All seemed to be roosting, very few were nectaring.”

While nectar sources have been depleted because of the drought, Frostweed, Poverty weed, purple aster, goldenrod, water hemlock and other late season bloomers awaited Monarchs’ this weekend,  But they didn’t seem interested.

A strange year, hopefully an aberration, but I fear that’s not the case.

Could 2012 be the Worst Year in Monarch Butterfly Migration History?

The mild winter, well-timed rains, and record wildflowers of spring 2012 resemble a lost dream as this year’s Monarch butterfly migration looks like it could be the worst in history.

Parched Goldenrod on the Llano River

Parched Goldenrod on the Llano River will serve no use to migrating Monarch butterflies except as a rest stop.

For a recap of the challenging year so far, read this post.

A visit last weekend to the Llano River reinforced the depressing outlook:   many of the usual nectar sources that fuel the migrating insects have been stopped in their blooming tracks by a lack of, or ill-timed rains and brutal heat this summer.  Declining river flow and a lower water table have contributed to the nectar shortage.

Goldenrod, usually a magnet for migrating Monarchs this time of year, stood parched along the riverbank–brown, crisp, and useless to the absent migrants, except perhaps as a rest stop.  Some stalks still remained green and those on the “Chigger Islands,” as we call them, offered only a few blooms.  Any nectar plant more than a foot from the riverbank was dead, except for Snow-on-the-Mountain.

Frostweed, a Monarch butterfly favorite, was much more scarce than last year–surprising given our better rains.   In the “historic drought” of 2011, Frostweed still thrived, but I’m guessing the timing of our rains and the Llano’s failure to recover lowered the water table so dramatically that plant roots were left dry. The 2012 Frostweed crop looks to be half or less than last year.

Frostweed

Some Frostweed showed its blooms on the Llano River last weekend, but not as much as we usually see in September.

Swamp Milkweed, typically a favorite host to Queens and Monarchs laying eggs along the river, showed scrawny, wilted leaves with blooms mostly spent.   We did find some eggs, though, and brought them home for fostering.

In my San Antonio butterfly garden, Monarchs are scarce.  I’ve seen only five so far and tagged ONE.  Last year at this time I had seen many and tagged two dozen by now.

A recent visit to the San Antonio River Milkweed Patch resulted in two Monarch sightings.   “We’re not seeing anything here,” said Mary Kennedy, a Monarch Larvae Monitoring Project volunteer and former science teacher, of her Fair Oaks yard just west of San Antonio.

Monarch butterfly on Water Hemlock

Monarch butterflies opt for Water Hemlock when their favorite nectar sources are not available.

Dispatches from Facebook and the Monarch butterfly DPLEX list sound equally discouraging.  ”I live on an acreage, and for the past 12 years, my small woods has been a roosting site,” wrote Anna Nicholas of Shell Rock, Iowa, on the DPLEX list, an email listserv that reaches hundreds of Monarch butterfly enthusiasts and scientists.

Nicholas relayed that in good years, Monarchs visited by the thousands. In bad years, only a couple hundred formed roosts. “So far… in the past week, I’ve seen three butterflies total,” she wrote.  ”Throughout the summer, I seldom saw a Monarch. I never found a caterpillar on any of my milkweed. I’ve checked with friends and family members…all report the same thing. In various parts of Iowa, there simply are no Monarchs. It’s very sad.”

“Been seeing any Monarchs?” asked the Native Plant Society of Texas on Facebook recently. Answers were overwhelmingly no, and then this report from Shauna Feely of Dallas:

I have not….However, I’m in a section of Dallas county that was aerially sprayed [with insecticides] , due to West Nile virus. A definite lack of birds and bees around here….We had a very active garden, but the spraying has put a damper on things….

Aerial insecticide spraying creates an extra challenge for the migration.

And then we see isolated reports of record Monarch sightings, like this one from Pennsylvania:  ”Observers at Hawk Mountain Sanctuary on the Berks-Schuylkill county line counted 2,806 monarch butterflies moving past the hawkwatch site on Monday,” reported the Pennlive website on September 11.  The tally set a one-day record at the sanctuary, Mary Linkevich, director of communications and grants, told reporter Marcus Schneck.

It’s still early in the season for the “Texas Funnel,” the strategic gateway through which all Monarch butterflies must pass en route to and from their ancestral roosts in Michoacan, Mexico.  So far, signs suggest a dismal year.  Continued rain like this weekend’s could change the forecast somewhat, perhaps coaxing late season Frostweed to push out more blooms, but nothing will resuscitate the crispy flower stalks we saw on the Llano.

Monarch Watch issued its periodic Monarch Population Status Report August 30, predicting the Monarch butterfly population this year “might be the largest since 2003– perhaps 6-7 hectares” if the weather cooperated.  Or, they speculated, we would see “another overwintering population in the 2-3 hectar range,” the worst since records have been kept.

I hope I’m wrong and am sad to say that I think it will be even worse.

Here’s How to Track the Monarch Butterfly Migration from Your Desk

The Monarch butterfly migration is underway.   Early reports from Canada suggest they’re embarking on directional southward flight, the first sign that migratory behaviour is afoot.  Next, they’ll start roosting.  Meanwhile, Monarch watchers in the northern reaches are reporting FOS (first of season) sightings.

 Monarch butterflies are on their way

Coming soon to nectar sources near you: Monarch butterflies

We generally see Monarch butterflies at our Llano River ranch during Labor Day weekend, but I saw my FOS in Austin last week.  Another graced my San Antonio front yard garden on Tuesday.    Given our hepped up weather pattern, an early migration seems likely.

In his periodic state-of the-union message assessing this year’s Monarch butterfly population August 20, Dr. Chip Taylor of Monarch Watch suggested the migratory population will be small this year, occupying only three hectares once they arrive in Mexico.  Taylor cited   a “year like no other” in the 117 years that climate records have been kept, with crazy weather and drought resulting in a late season lack of nectar and host plant sources.  As we wrote last week, wildfires in Oklahoma and aerial spraying of insecticides in a battle against West Nile virus in North Texas and now elsewhere could further complicate Monarch’s migratory journey.

That makes tracking Monarchs this year even more interesting than usual.  The good news is more resources for following their progress exist than ever. I’ve listed my favorites below.

Twitter Search

Using Twitter as a search engine is my favorite Monarch butterfly tracking tool.  It provides real-time updates of Monarch butterfly sightings.   Granted, not everyone uses Twitter, but for those who do and are interested in clocking the migration in real-time, it can be indispensible.

Twitter is a free, real-time search engine, as well as a broadcast outlet for individuals and organizations.  That means you can visit  http://search.twitter.com and punch in “monarch butterflies” or “monarch migration” or “monarch butterfly” and dozens of hours-old “tweets”–brief 140-character updates—will be returned, telling you where Monarchs are flying RIGHT NOW.

Twitter was conceived as a mass text messaging tool, thus the brevity of the updates.  It refreshes constantly.  And to use Twitter as a search engine, you don’t even need to open an account.

Twitter search ONLY indexes recent updates.  Google and other search engines are more akin to archives for the entire web.   You can try searching Google News, but this won’t return the on-the-ground reports Twitter delivers.  Like these, from today:

The results from these searches paint a real-time picture of what’s happening with the Monarch migration NOW.  Yes, there’s junk in there, but also insights, relevant news stories, photos and facts.  By clicking on the Twitterer’s profile, you learn their location.

Don’t scoff.  Give it a try and check out this Twitter search for the Monarch butterfly migration.

Monarch Watch Facebook Page

If you’re reading this blog and you’re on Facebook, then you likely have already “LIKED” the Monarch Watch Facebook page.  If not, go ahead, do it now, and join the party.  (And while you’re at it, why not LIKE the Texas Butterfly Ranch Facebook page?)

With more than 8,700 fans, Monarch Watch’s page serves as a delightful online plaza where the Monarch Watch team from the University of Kansas engages with the rest of us to share information, photos, and wax passionate about Monarch butterflies and their migration.   Citizen scientists, recreational observers, and professional and amateur biologists and entomologists join the conversation.  Like this:

Monarch Watch on Facebook

I almost always learn something from the Monarch Watch Facebook page.  Here, veteran caterpillar wranglers offer wisdom born from hundreds of hatched chrysalises, newbie enthusiasts pose curious questions and the sharp folks at Monarch Watch and the crowd set inaccuracies straight.  The photos are often amazing, like the one above of Monarchs “doing it.”

Journey North

Billed as the nation’s premiere citizen scientist project for children, Journey North tracks wildlife migrations and seasonal change.   This time of year, they post a weekly migration update on Thursdays based on observations from Monarch butterfly enthusiasts of all ages, from Canada to Mexico.   Here’s an excerpt from a recent report:

First Signs in North Observers in Canada reported directional flight for the first time this week, a clear sign of migration:

“Monarchs flying in a southwest direction at the       Kenesserie Tallgrass Prairie. Monarchs have been very common at this prairie site all summer, but now they are flying in the same direction rather stopping to browse for milkweed or nectar.”
8/19/12 Highgate, Ontario

Watching the Map
 We’re expecting the first report of roosting monarchs any moment. The shift to roosting behavior is another sign of fall migration, and is typically first reported from northern latitudes by now.

The Journey North website is specifically written for children and educators, and its teacher tone can be grating to those further down the road in their Monarch educations.   That said, the site offers loads of useful tools and resources for teachers and others on the Monarch butterfly migration.

Journey North's Migration App

Journey North recently launched an app for tracking the Monarch migration.

Journey North recently launched a laudible app that allows citizen scientists to post sightings of migratory species from their phones.   Check out the app and sign up if it suits you.

Monarch Watch Website

Journey North devotes itself to wildlife migrations besides Monarch butterflies (they also monitor hummingbirds, whales and birds), but the Monarch Watch website brags Monarch butterflies, all the time.

Monarch Watch website offers Monarch info 24/7/365

Based at the University of Kansas at Lawrence, Monarch Watch founded the citizen scientist tagging program embraced by thousands of us who tag Monarchs each fall.  Its comprehensive website offers information on how to tag a Monarch, raising milkweed, rearing Monarch caterpillars, and a database of all the Monarch tags recovered in Mexico, so those of us who tag can find out if any of our butterflies made it home.

The site also posts predictions for when the peak migration will occur at your latitude based on Monarch Watch scientists’ well-researched opinions.  The Monarch Watch blog is also worth a look.

D-Plex List

If the above won’t sate your migration curiosity, then consider signing up for the D-PLEX list,  an email exchange that includes about 650 scientists, conservationists, enthusiasts, and others, including some very interesting characters.

Named after the Monarch butterfly’s Latin designation, Danaus plexipus, the D-PLEX is an old fashioned email listserv started by Dr. Taylor and invites the public.  Sign up to receive D-PLEX emails on the Monarch Watch webpage.

Careful, though.  The D-PLEX can overtake your email inbox.   Conversations can escalate to generate dozens of emails a day, many of which you may not find useful.   I’ve set up all D-PLEX emails to forward to a special email box that I check once a day, so as not to be overwhelmed.

Don’t forget to check in with us here at the Texas Butterfly, too.  We’ll do our best to keep you posted.
