I spend a lot of time and quite joyful energy in July looking for hummingbird moths, those remarkable lepidopteran mimics of avian hummers. So far, alas, my usual go-to spot—my daughter's Gooseneck Loosestrife flowers in her garden—have not been visited by the insects, and it's too early for the Bee Balm at the Preston Nature Preserve, my other reliable venue for members of the Hemaris clan, to be drawing in the Clearwing Moths. But there are, I discovered, other lepidopterans with clearish wings and hummingbird tendencies. This one I noticed on the Swamp Milkweed blooms in the pollinator garden at Wilcox Park in Westerly. After considerable study, I learned that it's the adult, and a rather pretty one at that, of the Squash Vine Borer, whose larvae are dreaded pests of squash plants everywhere. It's considered more a wasp mimic than a hummingbird lookalike—notice those "feathered" legs that are supposed to look like those of a wasp—but it definitely hovers, so it appears that evolution has been inspired by two different lifeforms.
