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
