A male Monarch butterfly, tag number WMX658, paused Saturday morning October 1 around 11 AM on a fresh Frostweed bloom along the Llano River. Netted and retrieved, the faded Monarch was photographed, then released to set sail for his flight to Mexico.
Roach said by phone that WMX658 was one of 15 butterflies tagged that day. About 350 miles later, I netted the butterfly in Kimble County near London, Texas.
“It seems the migration is more consistent this year than I’ve ever seen. Every day there’s been a few,” said Roach, who usually tags between 100-200 butterflies annually. The day WMX658 was tagged, butterflies were nectaring on Smartweed, a member of the Polygonum family. Roach said a school outing was planned for that Thursday, but somehow the kids couldn’t make it so he just tagged with staff.
It was a first for me as well. In 11 years of tagging more than 3,000 Monarch butterflies with 29 recoveries, I had never netted a Monarch tagged elsewhere.
Many Swamp milkweed stands, Asclepius incarnata, that exhibited packs of aphids, milkweed beetles and bugs just two weeks ago, were now washed clean, losing lower milkweed leaves to “drowning” by water levels that rose 4 – 6 feet. Seedpods have replaced the pink flowers while other late season bloomers drew literally thousands of butterflies.

Frostweed, Verbesina virginica, was a favorite draw for Queens, Spangled, Gulf and other fritillaries, Giant, Pipevine and Eastern Swallowtails, skippers, snouts, sulphurs–everyone swarmed to the nectar fest that the recent weather pattern has made possible. And the wilted, yellowed, washed out milkweed leaves didn’t stop Monarchs and Queens from laying their eggs on remaining healthy foliage. At least one more hatch will occur before peak migration arrives the last two weeks of October.
“I looked outside and it was like a butterfly highway,” said Rebecca Guererro, a stylist at Mint Salon in downtown San Antonio on Thursday.
Monarchs have begun showing up in steady trickles in these parts just in the last week. The storied migrants were pushed south by a recent cold front and the dry-wet weather has set the stage for a bounty of nectar.
Dr. Chip Taylor of Monarch Watch issued a migration update on September 26 predicting a late migration this year.
“A while back I pointed out the probability that the migration would be late and long this year. That is likely to be the case,” said Taylor, pointing to hot weather as the cause. “Last week was a scorcher through much of the midwest with temperatures in the 90s and high-80s over a broad area. The migration advances slowly, if at all, under these conditions. The ideal temperatures for the migrants are in the 70s and 60s,” he said.
The Journey North website reported streams of Monarchs heading south through the central and eastern flyways. The site attributed the movement to a cold front that “dropped down from the north and finally ended the unseasonably hot weather — with associated south winds — that have been holding the butterflies back,” wrote Elizabeth Howard, founder of Journey North, in last week’s Thursday migration newsletter. Howard cited peak flights along the ridges of the Appalachian Mountains over the weekend as “the first strong pulse in the Eastern Flyway.”

How does he know where it was tagged? I found/photographed a tagged Monarch up here in IL. I called in the tag number but was told that since tags were still being sent out….they couldn’t tell me where my butterfly had been tagged from. I would really like to know

Besides calling in the tag number, you can put an email on the DPLEX list announcing that you found a certain tag, use social media like Facebook and Twitter, and call in the tag number. I know a lot of folks in the Monarch community, so that helps, too. There’s also a new Facebook page called Migrant Monarch Tag reports–https://www.facebook.com/groups/1453716944645673/?ref=ts&fref=ts . Good luck! –MM
