The Blue Dasher (Pachydiplax longipennis) can be found all over the Slope right now. My wife spotted one buzzing around in the skylight at The Lighthouse on Fifth Avenue. I saw several hovering over the patio at The Gate early last week. The specimen below was taking a rest on some plants in front of a brownstone on Carroll Street.
Dragonfly larvae are aquatic, and the young of this particular species are fairly tolerant of low dissolved oxygen, pollution and other environmental insults. Perhaps that's why they are the most abundant species in Brooklyn's skies. My guess is that the majority of those we see in the Slope are from Prospect Park and the Botanic Garden.
As the males mature, their abdomens turn completely blue, and their eyes turn from juvenile red/gray to a jade green/blue. I'm not really an odonate expert, but I'd say the specimen below is an almost mature male. (Are males of any species ever truly mature? I'll be he laughs at fart jokes.) Contrast this specimen's abdomen and eye color with a female dasher I posted last week.
I believe the small structures visible under the thorax just ahead of the juncture with the abdomen are mites, based on advice from nannothemis of Urban Dragon Hunters regarding an older photo of the same species.
