Damselflies

Damselflies are a challenge! There is almost nothing to them. They are virtually wisps of the imagination. And oh my! what identification mysteries they can.

Jon Lamm's wonderful little volume, Damselflies of the Northeast, uses three different symbols on the page of each species to indicate whether the species can be identified with (1) binoculars, (2) in the hand, or (3) under a microscope.

These damselflies are all identifiable with binoculars so I am reasonably confident I have gotten them correct.

Things with Wings - 3

Many dragonflies are an ID challenge, but nothing compared to the Damselflies.

In addition to Stokes Beginners Guide to Dragonflies and Dragonflies and Damselflies of the East by Dennis Paulson, a very good, and essential, resource is Damselflies of the Northeast by Ed Lam.

By way of illustrating the challenge of Damselfly ID, each species in this guide is accompanied by a symbol indicating the level of observation usually required for a damselfly to be identified to species:
  • in the field
  • in the hand
  • under the microscope
That said, the challenge of the damselflies is a rewarding one - these creatures are small, delicate, require alertness to see, and are often breathtakingly beautiful
