Four Fine Texas Moths for National Moth Week

Happy National Moth Week!   The celebration of the night flying cousins of butterflies, often cast as ugly step sisters in the world of lepidoptery, began only three years ago and takes place this week, July 15 – 27.

Wish I had planned better and organized an event.  Anybody?

Maybe next year. Dang work always gets in the way of the fun stuff.  Anyone interested in helping me organize a Moth Night in San Antonio, whereby we would set up a black light with a sheet and await/celebrate the arrival of moths, please leave a comment below.  Perhaps we can make something happen.

Meanwhile, you can still keep watch for some of the most common and amazing moths to be found in our area.  I had no idea how fascinating moths can be until I was seduced by butterflies. Turns out moths outnumber butterfly species 15 to one.  Really. That’s what happens….you start paying attention, and next thing you know, you’re raising caterpillars in the kitchen.

Here’s four moths that we have in Central and South Texas right now.  Open your eyes, look, and you will see them.

The Sphinx Moth

Known in its larval form as the much loathed Tomato or Tobacco Horn Worm, this attractive dusk flier also is often called the “hummingbird moth.”   Gardeners despise the Manduca sexta’s consumption of their tomato plants, but I suggest setting aside a few seedlings for these voracious caterpillars, who strike a sphinx-like pose when poked, arching their neck and staring blankly at who’s bothering them.

As moths, these impressive striped flyers move during daylight hours, hovering like helicopters to nectar and provide great observation opportunities.  They are members of the Sphinginae family.

Black Witch Moth

Large, bat like and harmless, the intriguing Ascalapha odorata, sometimes known as “the bat moth” resembles a bat in size and shape, and with its seven-inch wingspan is the largest moth in North America. They are common in these parts.

They often hang out near doors and flush when approached, causing quite a startle for the unsuspecting.  But remember, they’re completely harmless.   Much folklore surrounds their appearance.  Throughout the hemisphere, legend has them bringing good luck, a lottery win, or a death in the family, depending on the part of the world and the circumstances of their appearance.

In the movie Silence of the Lambs, serial killer Hannibal Lechter inserted cocoons of Black Witch Moths into the mouths of his victims as a weird gesture of transformation. The moth on the movie poster is a Death’s Head Hawk Moth, but the actual cocoon was that of a Black Witch.

Polyphemus Moth

The Polyphemus Moth, Antheraea polyphemus, sports prominent, owl-like eye spots and  a six-inch wingspan.  The moth is dramatic.  We had a hatch of these guys at the ranch one night and several fluttered against the porch spotlights.  The sound of their wings hitting the the floodlight was so loud, you would have thought birds or bats had paid a visit.

The Polyphemus gets its name from the Greek myth of the Cyclops Polyphemus (cyclops means one-eyed giant). They’re not unusual and live everywhere in the U.S. and Canada.   That they host on a variety of trees–oaks, birches, elms, willows and others–perhaps explains their widespread provenance.

Like many moths, these members of the Saturnid, or silk moth family, spend most of their life as caterpillars, eating up to 86,000 times their body weight at emergence in just two months.  Once they become a moth, however, their vestigial mouth parts make eating impossible.  Basically, their mouths don’t work any more.   Their sole focus as a moth is to reproduce.

Polyphemus change dramatically during the caterpillar cycle and in their final instar become a fantastic three- or four-inch green caterpillar with silver and/or red spots on the side.   See the photo above by our friend Mona Milller.

Ailanthus Webworm Moth

The first time I spotted one of these handsome creatures at the ranch I thought it was beetle.  They tuck their wings in a tidy fashion, leading you to believe they are of a different genre, but no–they are moths.

Members of the ermine moth family, the small, striped Atteva aua caterpillars build communal nests in the Ailanthus tree by pulling leaves together with webbing and spinning cocoons inside the webs.    They are native to Central America, but migrate north in the summer and host on the Ailanthus tree, sometimes called the Tree of Paradise.   Both the AWM and the Ailanthus tree are introduced species that have adapted.  Non native, but gorgeous creatures.

Genista Moth Caterpillars Return to Llano River Mountain Laurels

Last May I posted a much-read report of an extreme outbreak of Genista Moth larvae on two treasured Mountain Laurel trees my family had transplanted to our Llano River ranch 10 years ago.

The post, “Squish remorse” — Genista Larvae on Mountain Laurels Create Caterpillar Quandary,” started like this:

“It was an odd day, digging up wild parsley in search of chubby, Eastern Swallowtail caterpillars for fostering and fun at home, followed by hours of trying to figure out a humane and responsible way to kill hundreds–no, thousands–of unwelcome critters decimating several precious Mountain Laurels.”

 

The Genista Broom moth caterpillar, Uresiphita reversals, occupied almost every leaf of the tree.   Sometimes called the Sophora worm, these moth larvae relish the toxic leaves of our native Texas Mountain Laurels, Sophora secundiflora.

A year ago, the voracious caterpillars were decimating the evergreen native, which produces a Kool-Aid perfumed bloom that typically signals the first days of spring.

At the time, I was concerned the ubiquitous caterpillars would kill the tree or prune it to a shadow of its former self.   Several sources assured me not to worry—it was all part of the life cycle.

Twelve months later, I’m happy to report that the Mountain Laurels in question have rebounded magnificently. See the photo below.

Genista moth caterpillars decimated this Mountain Laurel last year, but the tree bounced back nicely in 2014. Photo by Monika Maeckle

That’s the good news.

The bad news: the Genistas have  moved on to devour another Mountain Laurel further up the hill from their 2013 feast.   As Sandra Schwinn commented at the time:

“I have dealt with these for the last couple of years…. If there were just a few of them, it wouldn’t be so bad. Be prepared for a second onslaught, as that’s been my experience. In fact, last year, I battled them from spring into fall.”

Sounds about right.   While it’s reassuring that the caterpillar onslaught doesn’t appear to kill the plant, it does rob us of the next year’s purple blooms since Mountain Laurel flowers only occur on second year growth.

Given the apparent heartiness of the Mountain Laurel I will resist the urge to squish the Genistas, letting nature take its course and ceding their role in the food web as fodder for lizards, wasps and others.

2013’s Top Posts: Moths, Monarch Decline, How to Raise Butterflies, Move a Chrysalis

We close out 2013 as a banner year at the Texas Butterfly Ranch.  2013 marked our third year covering the life cycle of butterflies, moths and the plants that sustain them.  We published 35 posts this year and drew 107,000+ page views–up from 42,000 in 2012.   Thanks to all for reading.

The decline of the Monarch butterfly migration led butterfly news this year, with a post detailing the steady downward spiral topping the list.  Interestingly, posts about how-to-raise butterflies and what species of milkweed to plant also ranked highly–apparent responses to the severity of pollinator decline? Hmm.

Below, you’ll find the posts you enjoyed most in 2013.

Monarch butterflies in decline

Dire predictions became reality in November when news reports suggested that  only three million Monarch butterflies would make it to Mexico this year.  For the first time in recorded history, Monarch butterflies did not arrive at their ancestral roosts in Michoacán en masse by Day of the Dead, November 2.  Scientists were concerned at this historic tardy turn.

Only three million Monarchs made it to Mexico and may occupy only 1.25 acres of forest this year, a record low. Graph via Journey North

The 2012 season, acknowledged as the worst year for the insects population wise, counted 60 million Monarchs.  In prime years, they numbered 450 million.  Looks like 2013 will hold the dubious distinction of the year the migration came unraveled.

Dr. Chip Taylor, founder of Monarch Watch, relayed a similar prognosis earlier in the season when he told the International Butterfly Breeders conference that the butterflies would likely occupy only 1.25 acres of forest in the mountainous roosting grounds west of Mexico City.  At their height, the creatures roosted in 50+ acres of forest.

How unspeakably sad that the entire population of Monarch butterflies east of the Rocky Mountains could fit into a space smaller than a strip shopping center.

People are doing what they can to help Monarchs on the home front

Our two-part feature on How to Raise Monarch Butterflies at Home ranked a top post  with readers.   In April I wrote that I had collected Monarch eggs from milkweed in my  front yard. Subsequent posts detailed step-by-step how easy it is to raise Monarch butterflies at home.

We started with the eggs, watching them hatch and become tiny caterpillars.  We fueled their growth with fresh, pesticide-free milkweed, then followed their whole lifecycle to the chrysalis stage and finally their eclosure to a butterfly. You can do it, too.  Read the two-part series here.

Moths:  Underappreciated, extremely interesting

While we call ourselves the Texas Butterfly Ranch, we try not to be speciesists.  That is, we try not to give too much attention to one species over another—although that’s pretty much impossible given America’s love affair with the Monarch butterfly.

We agree that Monarchs and other butterflies seem to get all the press at the expense of their less celebrated, night flying cousins.  That said, we try to spread the love around.

In fact, two of our top posts in 2013 didn’t even discuss butterflies.  Instead, they profiled two of the more interesting moths you’ll likely find in your gardens.

This post on tomato hornworms ran back in June 2012, yet climbed easily into one of the top reads of 2013—18 months after it posted in the height of summer.   Perhaps because so little is written about moths?  Or maybe thanks to National Moth Week, a relatively new celebration launched by the Friends of the East Brunswick Environmental Commission (Friends of EBEC), a group of citizen scientists that focus on the fascinating flyers every summer.  Mark your calendar for National Moth Week 2014, July 19 – 27, as a week that will celebrate their existence.

The truth is that even butterfly loving vegetable gardeners often squish the tomato and tobacco hornworms, which feast voraciously on tomato, pepper and potato plants and other members of the Solanaceae family.  We encourage ceding a few fruits or entire plants to these dramatic caterpillars, which later morph into beautiful Sphinx Moths.

Then, our story on the mysterious, myth-laden Black Witch Moth: Large, Common, Bat-like, and Harmless drew lots of interest.

This “bat moth” resembles a bat in size and shape and its seven-inch wingspan ranks it as the largest moth in North America.  Black Witch Moths are common in Central and South Texas and frequently rest under the eaves of houses near doors, often startling folks as they arrive home.   Generous rains seem to have offered favorable conditions for them this year, as we had many questions about them.

The folklore surrounding these harmless nightflyers runs the gamut.  They can be a harbinger of death–or a sign that your future includes a winning lottery ticket.

Butterfly 911:  lack of host plant results in milkweed emergency

This post on a “milkweed emergency” drew plenty of views and the most comments of any post ever on the Texas Butterfly Ranch  (76).

The quandary of too many caterpillars and no milkweed to feed them continues to find readers, especially at the end of the Monarch butterfly season when nurseries and gardens have exhausted their host plant supplies.

Monarch on Milkweed

It takes a lot of milkweed to grow a Monarch butterfly. The caterpillars consume 200x their birth weight in milkweed leaves. Photo by Monika Maeckle

Every fall, we receive frantic emails, Facebook posts and even phone calls from people who have plenty of Monarch caterpillars, but no milkweed on hand.   A milkweed shortage pretty much defines the plight of Monarch butterflies throughout the migration landscape.

Frequently, folks will run out to a nursery and buy a fresh pot of milkweed, unaware that plants have been sprayed with systemic pesticides, which can last six months.   This post details how to avoid the sad experience of finding all your caterpillars dead from toxic poisoning the morning after you’ve served them polluted host plant.

How to Move a Monarch Chrysalis

If you can get your caterpillars to the chrysalis stage, they often will build their jade jewel in an inconvenient location.   A post that draws steady interest year after year answers the frequently asked question:  Is Relocating a Monarch Chrysalis OK?

Monarch chrysalis and butterfly

The answer:  yes, you may relocate the creatures once they make their chrysalis.

The post details a few tips on how to handle a Monarch chrysalis with care and do’s and don’ts for successfully relocating them.

Got Milkweed?  Updated guide to Texas milkweeds

Finally, rounding out our top posts of 2013, an updated Milkweed Guide: Choose Best Plants for Monarch Butterflies.    Given the news of the decline of the Monarch butterfly migration, the call to plant milkweed and other wildflowers to make sure pollinators—not just Monarchs—continue their life cycle becomes urgent.

We get many questions  in our emailbox regarding which species are best for San Antonio and Austin yards, ranches, or even a vacant lots that beg for a butterfly garden.   Our Milkweed Guide aims to point you in the right direction.

We’ve added a few links below to other favorite posts that we believe merit your time.   We hope they pique your interest.  Let us know by leaving a comment.

To all our readers, mariposistas, MOTH-ers, butterfly lovers near and far–cheers to a healthy, happy 2014.   Plant lots of wildflowers, host and pollinator plants in 2014.   Stay away from pollutants and pesticides. Enjoy and tend your gardens and wildscapes.

See you outside.

Yo soy Mariposista! Butterfly Advocates Unite as Lepsters, MOTH-ers and Butterflyers

On a recent trip to Huatulco, Mexico, I was invited by the local guiding association to talk about the hobby of “butterflying.”  My Spanish is pretty decent since my husband and I lived in Costa Rica and El Salvador for years and now reside in San Antonio, a city closely tied to Mexico and populated largely by those who speak Spanish.  We embrace the language and enjoy speaking it.

Costa Rican butterflies

Too bad I wasn’t a mariposista when I lived in Costa Rica in the 80s. Could have seen all these beauties. Photo via nature.berkeley.edu

But I was stumped when attempting to come up with a word in Spanish that describes butterfly watcher.  “What is the word for birder?” I asked our guide Cornelio Ramos Gabriel.

Pajarero,” he said, suggesting the literal translation of “one who birds.”  When I consulted my iTranslate phone app, it cited “observadores de aves,” that is, observer of birds.

When I asked Cornelio the Spanish word for one who butterflies, he paused.

Mariposero?”  he asked, since mariposa is the Spanish word for butterfly.

We agreed that we could use the word “mariposero” for one who “butterflies”–but somehow it didn’t seem to catch what I meant.

As mentioned above, my husband and I lived in Central America during the Sandinista revolution and the Contra war–he, covering the wars of the region for Newsweek magazine and me as a magazine and newspaper freelancer.  I came to know the Spanish suffix “ista” as an add-on to any word that meant one who advocates for a certain belief.

Sandinistas, inspired by the failed revolution of Augusto César Sandino in the 1920s, overthrew the Somoza dynasty in 1979.  Panistas, on the other hand, pushed for the conservative, pro-business agenda of the National Action Party of Mexico while their counterparts, PRIistas, held power for nearly a century as Mexico’s ruling party, the Institutional Revolutionary Party.  In Argentina, Peronistas keep alive the progressive socialism of former president Juan Peron.  An anarquista, or anarchist, of course, would oppose all government.  And don’t forget, I was a periodista, or one who writes for a newspaper.

Given my fascination with languages and penchant for advocating for butterflies, it came to me:   Yo soy mariposista.

That word suggests a certain activist bent–just like Sandinista, Peronista, PANista, PRIista, all of which are political terms that connote a movement or advocacy of a point of view.

By such a definition, I am, indeed, a mariposista.    Yo soy mariposista, one who advocates for butterflies.

Por qué las Mariposas?

Back here in the U.S.,  “butterflying,” that is, the act or hobby of watching butterflies for fun, is in its infancy.  Many argue that butterflying is where birding was in the 60s.  More on that in a future post.

Just a little bit of research suggests that in English “butterflying” as a verb was likely first used in 1776.  According to our friend Nigel Venters in Cordoba province of Argentina, “the earliest reference is a short statement by Moses Harris, in the world’s first ever, well illustrated, and detailed book on butterflies in the late 18th century called “The Aurelian, or Natural History of English Insects; Namely Moths and Butterflies, Together with the Plants on Which They Feed.”   Yeah, really.  That’s the title of the book!

More recently, Robert Michael Pyle used the term “butterflying” frequently in his 1987 book “Handbook for Butterfly Watching.”

Apparently regional variations exist in the words used to describe those who watch butterflies, according to Monica Miller of Allegheny County, Pennsylvania.  Monica responded to my query posted on the DPLEX list, a butterfly listserv of hundreds of mariposistas, butterflyers and others.

“…I can confuse matters with the terminology we use up here in Pennsylvania,”  Monica  wrote via email.  “Since we include moths in our adventures, we refer to the collective targets as ‘leps’ and when we ‘lepsters’ go out looking we go ‘lepping’ as in  ‘Do you want to go lepping on Saturday?’ It’s more descriptive of what many of us do since a lot of us both butterfly and moth (both nouns and verbs there…)”

And speaking of moths, those who favor night flying lepidoptera point out that “MOTH-ers” are folks who prefer the observation of moths while “lepsters” go both ways, enjoying both the colorful beauties that grace our gardens during the day and the more mysterious creatures that pollinate plants at night.

Blue Morphos and a Butterfly Bonanza in Huatulco, Mexico

I made myself a rule several years ago to stop running blindly after butterflies with my net.   Too often I had done so, often in the Llano River, chasing Monarchs in the fall when they return to Mexico.   Sometimes I would trip on a rock, slip on wet limestone and narrowly avert catastrophe in the middle of nowhere with the closest hospital hours away.

Blue Morpho

But the sight of a Blue Morpho, one of the most beautiful butterflies on the planet, languidly tracing a dirt road from the tropical canopy of the Sierra Madre mountains in Mexico last week caused me to break my own rule.  Running full speed while looking up, I chased the butterfly for about 500 feet before tripping on a fallen branch.  Luckily I caught myself.  We were many miles from medical assistance.

I gave my net to Cornelio Ramos Gabriel, our able nature guide.   Within a half hour, Cornelio had nabbed a Morpho peleides, whose wingspan can reach eight inches and whose blue wing flashes have made the species a target of collectors in addition to its natural predators. We photographed the beauty and released her.  Cornelio told me that the dreamy flyer is relatively common in these parts, along with its dramatic sister, the White Morpho.  We saw several examples of both on our day trip to Finca Monte Carlo, a lovely coffee plantation in the Sierra Madre.

My five-day butterfly trip was the scheme of dear friend Veronica Prida, who with her husband Omar Rodriguez are the hosts of CasaTulco, a fabulous nature retreat set in the ecofriendly tourist destination of Huatulco, Mexico.  The resort lies in Oaxaca, about 300 miles south of Acapulco on the Pacific coast.

Veronica and I have been butterfly buddies for years and she was kind enough to assemble a butterfly trip that included me, butterfly guide book author Kim Garwood, and birder/photographer Susan Hoffert.  Cornelio and Mateo Merlin Sanchez worked hard as our guides, catering to our every whim as we made CasaTulco our base.  In the evenings, we lolled by the pool, recounted our adventures, and researched unknown finds as the entire CasaTulco staff attended our need for margaritas, chilaquiles and wi-fi.  It was a magnificent trip.

Superb Cycadian chrysalises

Our Blue Morpho outing took us on a two-hour spine-jangling, four-wheel drive jaunt up a dirt road that wound through tropical mountain forests and tracked a vibrant stream.   We saw 117 species of butterflies in just 48 hours.  Kim seemed nonplussed each time Susan or I pointed out a new find, patiently identifying its common and Latin names, her capacity for recall a stunning reminder of my own frequent forgetfulness.

“That’s a Fine Line Hairstreak,” said Kim upon one of my inquiries. “He likes roadside edges.”  Is that unusual?   “No.”

After a fruitful stop at a small cascada, or waterfall, where various Swallowtails and Sulphurs puddled and danced above the rushing water and an Owl butterfly hid in the thick underbrush, we arrived at Finca Monte Carlo.  Our gracious host, Efren Ricardez Scherenberg, escorted us directly to a mature cycad palm where a cluster of Superb Cycadian butterflies had just pupated.  The brown and black chrysalises, called capullos in Spanish, looked like designer chocolates from a high-end confectionary.

Efren explained that every year about this time the caterpillars and later chrysalises appeared, just for a short while.  He believed they would hatch the following morning, but  they did not.  He graciously shared the photo above just two days after our departure.

Our sojourn into the surrounding tropical forest lead us down a lovely mountain trail where a roaring spring-fed creek spilled over rocks under a thick canopy.   Birds were ubiquitous and insects in every stage of development invited photos and inspection.  That evening, a storm sparked a power outage and the full moon provided our light as a freshly hatched Black Witch Moth settled into the kitchen allowing for close inspection with a flashlight.

The surrounding grounds, lush with tropical vegetation and shade grown coffee, offered its own extravaganza of bird and insect life.   Mateo carried a spotting scope for close-ups, as Ulises, the sweet, very spoiled and friendly house cat, accompanied us on meanders through nearby Anthurium beds where dozens of enormous and varied bumblebees harvested pollen from the showy flowers’ spikes.

Interestingly, we also found some Tropical milkweed growing along the driveway’s edge.  On it, several eggs–either Monarchs or Queens.  Efren will let us know.

Large, Bat-like, Harmless: Black Witch Moths Making Appearances in South Texas

Black Witch moths are making themselves known in South Texas again. The large, harmless moths appear seasonally–we had one at the ranch this weekend.

Here’s a great shot from Karen Hermann of the fascinating creatures, which often roost in the eaves of front doors resulting in a creepy “startle factor” when they’re flushed by those returning home.  Special thanks to entomologist extraoridnaire Mike Quinn of Austin-based www.texasento.net for helping gather much of the info for this post.

The  intriguing Ascalapha odorata, sometimes known as “the bat moth” resembles a bat in size and shape and with its seven-inch wingspan is the largest moth in North America.  They are common in these parts.

Reports of large,  bat-like moths surprising people, frequently as they return home and are unlocking their front door, are not uncommon.   Because of their dramatic size,  when these big boys flush, they get your attention.

Black Witch Moth Caterpillar

Females have a white, sometimes iridescent stripe across their wings with wings open.  Males exhibit the plain, grey, brown mottled pattern commonly associated with moths, but with small dark eyespots on each forewing.   Black Witch Moth caterpillars eat legumes, and favor acacia and mesquite.   They are perfectly harmless, not an agricultural pest, and have no teeth or stingers.

The folklore surrounding Black Witch Moth, like the moth itself, is all over the map.  In Mexico they are known as “mariposa de la muerte,” the butterfly of death.   Some believe if a Black Witch Moth enters the home of someone who is ill, the person will die.

A variation on the folk wisdom suggests that the moth must travel to each corner of the house for death to occur.  The Mayans called the Black Witch x-mahani-nail, which means “the habit of entering buildings.” This moth apparently has a long history of inviting itself inside.

Interestingly, in the Carribean, the Black Witch Moth is known as the “Money Moth” and if it visits your home, you are likely to come into cash.   Here in South Texas, some believe if a Black Witch Moth roosts over your door, you will win the lottery.

Native to Central America and Mexico, the Black Witch starts migrating north in late spring.   The Black Witches’ seven-inch wingspan allows them to cover a lot of ground quickly.  Entomologists note that  Monarch butterflies start crossing the Rio Grande and take two months to reach Canada.  Black Witches start migrating in June and have been recorded

Hannibal Lechter used actual Black Witch Moth cocoons

Serial killer Hannibal Lechter inserted actual Black Witch Moth cocoons into the mouths of his victims in the movie, Silence of the Lambs.

reaching Maine by June 9 and Manitoba, Canada, by June 28.  That’s a rapid pace for a moth.  Scientists wonder why the Black Witch Moth migrates so far north with no southbound return?  Hmm.

In the movie Silence of the Lambs, serial killer Hannibal Lechter inserted cocoons of Black Witch Mothsinto the mouths of his victims as a weird gesture of transformation.   The moth on the movie poster is a Death’s Head Hawk Moth, but the actual cocoon was that of a Black Witch.

If you’d like to have one roost above your door to inspire a winning lottery ticket, you might try setting out a cocktail of fermented fruit or stale beer.   Black Witch Moths also like tree sap.  Good luck!

“Squish remorse” — Genista Larvae on Mountain Laurels Create Caterpillar Quandary

A mega hatch of Genista larvae on transplanted Texas Mountain Laurels along the Llano River created an uncomfortable “caterpillar quandary” for me this weekend.

Sophora worm, genista moth larvae

Not cool. Hundreds–no, thousands–of these Genista moth larvae, devoured our Mountain Laurels. Photo by Monika Maeckle

It was an odd day, digging up wild parsley in search of chubby, Eastern Swallowtail caterpillars for fostering and fun at home, followed by hours of trying to figure out a humane and responsible way to kill hundreds–no, thousands–of unwelcome critters decimating several precious Mountain Laurels.

The culprit:  the Genista Broom moth caterpillar, Uresiphita reversalis.   Sometimes called the Sophora worm, these moth larvae relish the toxic leaves of our native Texas Mountain Laurels, Sophora secundiflora.

We have painstakingly imported several of the gorgeous native evergreens to our stretch of the Llano, digging difficult holes for transplanting them in the Hill Country caliche and watching the slow growers progress over the last 10 years.  Mature Mountain Laurels are expensive at nurseries.  They serve as a harbinger of spring with their Kool-aid scented purple blooms, which alert us that ground temps have warmed, vegetables can be planted, and summer will be here too soon.

First I tried picking them off by hand.   Then I fetched a sheet from the ranch house and shook the bushes, watching as they fell by the dozens to the ground.   Finally I got a hose and blew them away with a high pressure jet of well water.    Those handpicked and retrieved from the sheet went into a jar that was placed in the freezer for a relatively painless death.

I felt bad. But my Mountain Laurels were decimated.  Genista larvae favor new growth and eat the buds and terminals of the Mountain Laurel first.  And that’s where the purple flowers form in the spring.  Interestingly, I had never noticed the abundant caterpillars in 20 years in Central and South Texas.

“They’re always around,” said Elizabeth “Wizzy” Brown, an integrated pest management specialist for Texas Agrilife Extension Service in Austin, dismissing my theory that something special was going on.   I read somewhere that Genistas are poisonous to birds, and speculated that perhaps that’s why they were left seemingly untouched by avian species.   Brown dismissed that.

She recommended BT- bacillus thuringeisis, the organic biological pesticide and all- around caterpillar killer.   When I let her know I garden for butterflies and moths–just not THIS moth–she suggested getting out the vacuum cleaner to suck them off the tree.  Wish I had thought of that.

Entomologist Mark Muegge, a Texas Agrilife butterfly expert out of Ft. Stockton, felt the pain of my “squish remorse.”

“I understand….I’m kinda the same way,” he said.  “Sometimes you have to use tough love.”

“They’re not a particularly attractive moth or caterpillar,” sniffed Mike Quinn, an Austin entomologist and founder of the useful Texasento.net website.   “There’s no aesthetic reason to not squish them. They’re a pest.”

Brown and Muegge both proposed that the Genista Broom moth’s purpose in the universe is to supply fodder for the food web.

Lizards eat them, the brilliant tachinid fly uses the Genista as a host, laying its eggs on the caterpillars, eating them from the inside out, and wasps also consume the Genista as food.  “They fit into the food web,” said Brown.

“Everything has its purpose,” said Muegge.  “What they’re good for is hard to say.”

According to Muegge, my reaction to the onslaught of caterpillars may have been extreme, an embarrassing admission for a butterfly evangelist.

“I have never seen a tree or shrub die from being defoliated,”  he said.  “They’ll stress, but they’ll come back.”

And, fortunately or not, so will those caterpillars.

Catalina Trail, Dr. Chip Taylor, Black Witch Moths, Tomato Hornworms and IMAX Movie make Top Posts of 2012

What were the most-read stories at the Texas Butterfly Ranch this year?  Beyond the homepage and the “about us” tab, these were the most widely read posts over the past 12 months.  Take a look and happy holidays to you.

#1  Catalina Trail, founder of the Monarch Butterfly Roosting Sites, Lives a Quiet Life in Austin

Our most-read blogpost written in 2012 is the story of Catalina Trail, a lovely, quiet woman who ‘s role in Monarch butterfly natural history was relatively uncelebrated until

recently.    We consider it a privilege to have made her acquaintance and found a friend in Catalina this year.    She lives just 75 miles up the road in Austin, Texas.

#2   The Intriguing Black Witch Moth, Large, Batlike and Harmless

This enormous dark, batlike moth loves to rest under eaves and around doorways, a habit that results in quite a “startle factor” when flushed, as explained by our friend and

entomologist Mike Quinn.  The drought seems to have helped the moth’s population grow and extended its migration, making it more common than usual this year.

#4 Desperately Seeking Milkweed:  Monarch Butterflies Appetites Create Milkweed Emergency

This post created a bit of a stir, as it called out a local nursery for selling chemical laced milkweed to a friend who was feeding hundreds of Monarch caterpillars.   Read on

for tips on determining if milkweed bought from local nurseries is riddled with systemic pesticides that spell death for Monarch caterpillars.

#4  Tomato Hornworms, Loathed by Gardeners, Morph into the Magnificent Sphinx Moth

Gardeners often can’t tolerate the tomato hornworm, which appears in early summer and decimates those heirloom and cherry hybrids so painstakingly tended.   But the chubby

green “worm” is actually a caterpillar that morphs into a gorgeous pink-and-black moth that hovers and dances much like a hummingbird.

#5  Chasing Monarchs on the Llano River with Dr. Chip Taylor

It was a butterfly evangelist’s fantasy come true, to tag Monarch butterflies with one of the foremost experts on Monarchs on the planet, Dr. Chip “Orly” Taylor, founder of

#6   FAQ:  Is it OK to Move a Monarch Chrysalis?

This post gets a lot of action when folks find a lonely Monarch or other butterfly chrysalis in an inopportune spot.    We frequently are asked if it’s ok, and if so, how to relocate the

chrysalis to a safer, perhaps more welcoming place.  Here’s tips on how to do it.

#7 IMAX Film Might be as Good As it Gets for Monarch Butterflies 

The fabulous IMAX film, Flight of the Butterflies, opened in September, just as we were anticipating the Monarch migration.    All the hubbub surrounding the film’s debut made it seem that the 3D footage assembled by SK Films might be as good as it could possibly

get for Monarchs this year–and that is likely the case.   Monarchs may have had their worst year yet, numbers-wise.  Texas Butterfly Ranch later reviewed the film in this post.

Other favorite posts that were written in years past:

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.

Black Witch Moth: Large, Common, Bat-like, and Harmless

In European folklore, moths were regarded as witches.  Not a big stretch.  Witches are creatures of the night.  Moths are creatures of the night.  Witches can transform themselves….  Moths can transform themselves (metamorphosis)…. Witches fly.  Moths fly.  Witches have long noses.  Moths have long noses.

–John Himmelman, in the book, Discovering Moths

All hail the Black Witch Moth.  It might be a harbinger of death–or a sign that your future includes a lucky lottery ticket.

The  intriguing Black Witch Moth, sometimes known as “the bat moth” resembles a bat in size and shape and with a a seven-inch wingspan is the largest moth in North America.  They are common in these parts.

”People often come across it by causing it to fly up and around them,” said entomologist Mike Quinn, who has been tracking the migration of Ascalapha odorata for his Texasento.net website.  “There’s a real startle factor.”

Reports of large,  bat-like moths surprising people, frequently as they return home and are unlocking their front door, are not uncommon.   We spooked several Black Witch Moths on a recent visit to the Santa Ana Wildlife refuge in the Rio Grande Valley, where they roosted under wooden benches and in the eaves of the breezeway near the entrance to the visitor center.    When these big boys flush, they get your attention.

Females have a white, sometimes iridescent stripe across their wings with wings open.  Males exhibit the plain, grey, brown mottled pattern commonly associated with moths, but with small dark eyespots on each forewing.   Black Witch Moth caterpillars eat legumes, and favor acacia and mesquite.   They are perfectly harmless, not an agricultural pest, and have no teeth or stingers.

The folklore surrounding Black Witch Moth, like the moth itself, is all over the map.  In Mexico they are known as “mariposa de la muerte,” the butterfly of death.   Some believe if a Black Witch Moth enters the home of someone who is ill, the person will die.

A variation on the folk wisdom suggests that the moth must travel to each corner of the house for death to occur.  The Mayans called the Black Witch x-mahani-nail, which means “the habit of entering buildings.” This moth apparently has a long history of inviting itself inside.

Interestingly, in the Carribean, the Black Witch Moth is known as the “Money Moth” and if it visits your home, you are likely to come into cash.   Here in South Texas, some believe if a Black Witch Moth roosts over your door, you will win the lottery.

Native to Central America and Mexico, the Black Witch starts migrating north in late spring.  “The migration has been going on since June,” said Quinn.  Because of our timely rains and climate change, several Black Witch Moth “records” have been set, meaning the moths have appeared further north earlier in the year than ever.

Black Witch Moth Records 2012

More than 500 Black Witch Moth Records Have been set in 2012. For details, click on the map. Map courtesy www.texasento.net

“This year may end up as the best year yet for Black Witch Moth (BWM) records,” wrote Quinn to the University of Houston Texas Butterfly Listserv, which includes more than 250 novice and professional lepidopterists.   Quinn has recorded more than 500 records so far, including a significant record in Maine, in mid June.

The Black Witches’ seven-inch wingspan allows them to cover a lot of ground quickly.  Entomologists note that  Monarch butterflies start crossing the Rio Grande and take two months to reach Canada.  Black Witches start migrating in June and have been recorded

reaching Maine by June 9 and Manitoba, Canada, by June 28.  That’s a rapid pace for a moth.  Scientists wonder why the Black Witch Moth migrates so far north with no southbound return?  Hmm.

 

In the movie Silence of the Lambs, serial killer Hannibal Lechter inserted cocoons of Black Witch Mothsinto the mouths of his victims as a weird gesture of transformation.   The moth on the movie poster is a Death’s Head Hawk Moth, but the actual cocoon was that of a Black Witch.

If you’d like to have one roost above your door to inspire a winning lottery ticket, you might try setting out a cocktail of fermented fruit or stale beer.   Black Witch Moths also like tree sap.  Good luck!

Happy Moth Week! Night Flying Butterflies Finally Get Some Respect

Butterflies,  Monarch butterflies in particular, seem to get all the press–and yet their night-flying cousins can be equally endearing and beautiful, providing useful pollination and food chain chores for our greater good.  Vastly under celebrated, moths are finally getting some well-deserved attention thanks to the first National Moth Week, July 23 – 29.

First National Moth Week, July 23 – 29, 2012

Started by several environmental scientists and insect enthusiasts in East Brunswick, New Jersey, National Moth Week grew out of occasional celebrations the group enjoyed hosting “Moth Nights” on the east coast and rides on the citizen scientist movement typified by Monarch Watch.   At a Moth Night, enthusiasts gather in the evenings with sheet-covered lights and old beer to draw the night flyers in for close inspection and photographs.

Interested?  If so, leave a comment.

The National Moth Night website offers a wealth of resources, including step-by-step instructions for hosting a Moth Party and recipes for making Moth Bait, which often features stale or fermented fruit, sugar, beer or wine.  Moths are literally suckers for stale beer.

“Basically, we want people to go out and have fun,” David Moskowitz told  Southern Rhode Island Newspapers.  Moskowitz, a New Jersey-based biologist who also works as a senior vice president for environmental consulting firm EcolSciences, collaborated with New Jersey oceanographer Liti Haramaty to get National Moth Week off the ground.

“If we can use National Moth Week to turn them on to what’s in their own backyard, then hopefully something will click and they’ll start to think twice about environmental issues like recycling, and preserving habitats and biodiversity,” said Moskowitz.

Why is it that moths don’t get the attention and respect of butterflies?

Most are grey or brown, which makes them more drab than visually appealing.   Their erratic flight pattern can be creepy.   Flailing around and diving at lights can put people off.   Moths’ habit of coming out at night also raises some shackles and perhaps unpleasant, scary associations.  And then there’s the fact that much of our contact with moths amounts to finding them ruining our sweaters and winter wear.

Some people even have a fear of moths, called mottephobia.  “Motte” means “moth” in German.

As we’ve written here before, the 1991 thriller The Silence of the Lambs, starring Jodi Foster as tenacious cop Clarice Starling and Anthony Hopkins as cannibalistic serial killer, Hannibal Lecter, didn’t help moths’  reputation.  In the award-winning movie, “Hannibal the Cannibal” places the cocoon of a certain species of hawk moth, the Death’s Head Hawk Moth, in the mouths of  his victims as some sort of sick gesture of transformation. The moths fly around in a creepy, dark basement and evoke a weird terror.

The thriller, Silence of the Lambs, has contributed to moths' creepy reputation.

The thriller, Silence of the Lambs, contributed to moths’ creepy rep.

But not all moths are scary or ugly.  The Sphinx Moth, for example, sports black, grey and white stripes and often is mistaken for a hummingbird.  It sometimes carries out its aerial ventures during the day, hovering on late afternoon blooms.

In the caterpillar stage, the distinctive creature sports seven black-dotted stripes on a plump green body, its namesake “horn” reaching from its rear-end.   When bothered, the caterpillar strikes a stately “sphinx” pose, arching its head and shooting an annoyed look.
