Spreadwing

A ready distinction between dragonflies and damselflies is that dragonflies perch with wings open and spread out while damselflies perch with their wings closed, parallel to their abdomen. That’s most damselflies. The regional exceptions: the Lestidae family spreadwings, and one of the pond damselflies, the Aurora/Chromagrion conditum.

This is one of the former, a Lestes genus spreadwing. The females can be hard to tell apart, but I think this a Slender/L. rectangularis.

I’ve never run across any of the spreadwings in Brooklyn. This one was on Staten Island. I’ve also had luck in Queens.
