A WSU-Tagged Monarch: What a Traveler!

Sep 6, 2016

What are the odds? What are the odds?

A monarch—the most special monarch ever--fluttered over our pollinator garden in Vacaville, Calif. on Monday afternoon, Sept. 5 and touched down on a Mexican sunflower (Tithonia).

As it sipped nectar, I glimpsed something white, round, and lettered, something I've never seen before in the wild. This one was tagged.

Shouldering my camera with a macro lens as long as a military tactical flashlight, I slowly edged around the garden, nearly hugging my new best friend, a cherry laurel hedge, as I tried not to look like a predator seeking prey.

Please, please, don't fly away. Stay still for a few minutes so I can read your tag. Please. Please. I want to know where you're from, how far you've traveled to get here.

As if on cue, Danaus plexippus stayed still and I shot away on the continuous mode setting with my camera, a Nikon D700 equipped with a 70-180 macro lens. It's a handy lens for fluttering monarchs and skittish insects that move in and out of your viewfinder.

But when I read the little round white tag, my eyes widened and I think I did a happy dance or a somersault or a pirouette. The tag, with a serial number, read “Monarch@wsu.edu A6093.” Oh, wow! This monarch is from my alma mater, Washington State University.

Where have you been, monarch@wsu.edu? I've been looking all over for you since Oct. 17, 2014 when I also encouraged others to look for you.

That's when I wrote a Bug Squad blog on WSU entomologist David James and his exciting monarch project.

The next time you see a monarch butterfly heading your way--or settled in at an overwintering site in coastal California or in central Mexico--check to see if it's tagged.

It may have flown hundreds of miles from the Pacific Northwest, and Washington State University entomologist David James is eager to know where you found it.

James, an associate professor at Washington State University,  studies the migration routes and overwintering sites of the Pacific Northwest Monarch population, which are thought to overwinter primarily in coastal California but also in  central Mexico. He spearheads a Monarch-tagging project in which volunteers--primarily inmates at the Washington State Penitentiary, Walla Walla--rear and release the butterflies.

And voila! There is monarch@wsu.edu A6093.

To put it frankly, A6093 and I became quite close. True-blue friends. Well, he's orange and black, actually. Still, it was a five-hour friendship. I first saw him at 1 p.m., and he hung around our pollinator garden for five hours. How did I know the gender? When he spread his wings, I saw the familiar black dots.

A6093 was exciting to watch. He'd pause to sip some nectar from the Mexican sunflowers and butterfly bush, and then soar upward again, meeting and pursuing other butterflies. He was part of a swirl of orange butterflies, a symphony of orange butterflies, dancing in the sky to music only they could hear.

But here's what's really exciting. We emailed entomologist David James of WSU and learned that the monarch was tagged by Steven Johnson of Ashland, Ore. and released on Sunday, Aug. 28. “Information is slowly trickling in,” he wrote back today. “I think it likely that Steven reared it from an egg laid on his property."

"So, assuming it didn't travel much on the day you saw it, it flew 285 miles in 7 days or about 40.7 miles per day.  Pretty amazing. So, I doubt he broke his journey for much more than the five hours you watched him--he could be 100 miles further south by now."

"Clearly this male is on his way to an overwintering colony and it's possible we may sight him again during the winter in Santa Cruz or Pacific Grove!”

Maybe we'll get more tagged monarchs? "You could well find another tag in your yard!" James said. "We believe they do take defined routes (valleys, rivers) so you may well be on a 'route.'"

So apparently our yard was a fueling stop or an "oasis," as James put it. "The tagged male--had you been able to look inside its body--would have been full of 'fat body' and a very reduced reproductive tract..so his interest in the opposite sex is currently minimal..and it'll stay that way until Feb 2017!"

(Editor's note: If you see a WSU-tagged monarch, take a photo and let WSU know. Contact monarch@wsu.edu or the Facebook page. For more information about the project, see WSU's monarch butterfly news story about inmates' tagging project, and a news story on monarch decline.)
