Hanging the Night
This Twelve-spotted Skimmer (Libellula pulchella) was parked just off the path around 730pm, so I think it was roosting for the night. The black markings looked velvety in the light.This is a mature male. If you counted the white spots, too, he would be a twenty-spotted skimmer. To matters more confusing, this species used to…

I’ve posted previously about separating these from the similar American Lady butterflies (Vanessa virginiensis); from this view, the four big wing spots mark the Painted; two big spots the American.Orange Bluet (Enallagma signatum) male. Small and slender, but striking when you see it: at Green-Wood’s Sylvan Water. At the nearby Valley…

Dragonfly Days of Summer
Male Common Whitetail (Plathemis lydia). Very distinctive. Here’s another view of another:The tail is slightly bluish, actually. Great example of pruinosity, the waxy bloom (can be blue, gray, or white) on mature odonates, especially males. Dragonfly season is upon us. During this weekend wanderings in Brooklyn Bridge Park, Green-Wood Cemetery, and Woodlawn Cemetery, I saw…

This is the adult stage.We saw many antlion traps, where buried…
