Summer won't be over for a while in my book—not as long as there are dragonflies around. I think I've seen more dragonflies this year at the Chicago Botanic Garden than I have in the past ten years combined. The quick, strong fliers seem to be everywhere.
A Half Male, Half Female ButterflyAt Butterflies & Blooms on Monday, I saw something I had never seen before in my five years as a butterfly wrangler at the Chicago Botanic Garden. I noticed that a leopard lacewing's right wings were bright orange, just like any other male of the species, but the left wings were beige—only females have beige wings. This lacewing was half male and half female, or a gynandromorphic butterfly.
One day at Butterflies & Blooms, I noticed a crepuscular, cosmopolitan imago puddling in order to prepare for an upcoming lek. What did I just say?The vocabulary surrounding Lepidoptera can be very specific—and not so easy to understand. Let’s break it down, and go over some of my favorite butterfly and moth terminology (and learn some of the amazing things these insects do). Then, see if you can decode the sentence above.
If you happened to walk around the Heritage Garden in late June, the unusual blue color of the Moroccan mountain eryngo (pronounced eh-RING-go), Eryngium variifolium, probably caught your eye, and its peculiar perfume tickled your nose. It was also swarming with flying insects.
At the Chicago Botanic Garden's Butterflies & Blooms exhibition, I receive a wide variety of questions about butterfly physiology. My favorite questions are ones that don’t have a substantiated answer, only theories posited by lepidopterists (or those who study butterflies and moths). I always enjoy these questions, since they are on the cutting edge of scientific understanding.One such question is: “What are those specs of gold on the monarch butterflies?” The short answer is “Nobody knows!” But there are a few interesting theories.
Today is National Migratory Bird Day, set smack dab in the middle of May—the month to look for warblers, vireos, thrushes, sparrows, and some shorebirds, as they migrate through the Chicago area.Most birders might agree that the highlight this time of year is warblers. It is for me—they are tiny jewels with wings. I feel totally blessed if I can see a few during migration.
