Hemaris thysbe (hummingbird moth).
During the first half of August last year, I was thrilled to discover not only butterflies at Perennial Garden, but also the little fairy moths known as snowberry clearwings (Hemaris diffinis). I’d seen one of their cousins, the hummingbird clearwing (Hemaris thysbe) in Ann Arbor a few years ago, but never expected to see anything like them here.
I found that great, Eastern tiger, and black swallowtails; red-spotted purples; painted ladies; silver-spotted and fiery skippers; bees; clearwings; and even a hummingbird or two love a particular butterfly bush at the garden. This bush, which had been cut down to the ground after last summer, didn’t bloom fully until early to mid-August—I started checking as early as May! On my brief visits, I never saw clearwings, so I braced myself for disappointment.
I started seeing a few a couple of weeks ago Thursday. When I pedaled over the Saturday before last at 3 p.m., the bush was swarming with life. I noticed that among the snowberry clearwings a few hummingbird clearwings, with their fuzzy green upper backs, were making an appearance. I was in heaven. I love these guys—even after I noticed they were buzzing one another and throwing each other off choice branches of blossoms.
By Saturday there were fewer of the hummingbird moths under the increasingly cloudy skies. I was happy to have seen so many the day before.
I’d made one of the photos I’d taken the background image on my iPhone screen. I’ve changed phones since then, but I haven’t changed the image. I took a closer look at it—and realized that particular photo from last year is of a hummingbird moth (Hemaris thysbe). How did I never notice that? It had the species’ distinctive fuzzy green upper back and lacks the light band near the skirt. While bemoaning that I hadn’t seen any Hemaris thysbe at this butterfly bush, I’d been staring at a photo of one I’d taken a year ago. Brilliant.
Last Tuesday I left work early for a doctor’s appointment and managed to get to the garden by 5 p.m. I was happy to have this unexpected opportunity to visit my little fairy moths—especially since they live only a few weeks.
The bush wasn’t buzzing like it’d been on Saturday, and there weren’t any large butterflies around—but there were enough moths for me to get a few photos and videos, including one in slow motion. I don’t know why I didn’t think of that sooner, except I am still trying to get a sharp closeup photo.
While I was standing watching a handful of moths flitting around, I heard a “bzzzzzzzzt” behind my head. I turned to find myself face to face with a hummingbird, separated by only a foot and a half or two feet of space.
As I was trying to get myself together (“Where’s the phone? Where’s the camera app?”), she buzzed around me to take a couple of quick sips at the bush. I have only these mid-distance shots and a memory now.
Now there’s only about an hour between the time I get home, change, get my bike out, and ride over, and sunset. By that hour, the Hemaris moths are few if any. The other day I was watching a hummingbird clearwing when a snowberry clearwing attacked it and carried it away.
I wish I could tell them there are plenty of blossoms to go around for the little time they have left.
