It’s easy to identify an ebony jewelwing (Calopteryx maculata) because no other northeastern damselfly has all-black wings. This is a male, and he’s guarding a territory and looking for mates. If a female comes by, she’ll signal her opinion of him using her wings: spread wings mean “Nope” and a wing flip means “Hey, hot stuff”.

Just a reminder that I’ve got a nature blog! It’s all photos that I’ve taken in the field, along with a little bit of natural history.
