Thanks again! I will definitely check out.
Another good reference: _Dragonflies and Damselflies of the East_ by Dennis Paulson (Princeton Field Guides) Princeton University Press. I recommend the Kindle Edition (great for quick searches and highlighting text).
Thanks. I will start looking at bugguide.net, it looks like a better research tool.
This is an Eastern Forktail damselfly (Ischnura verticalis). Fragile Forktail damselflies can be identified by their black thorax with two distinctive exclamation points (either blue or green, depending upon maturity); their abdomen isn't blue-tipped like the Eastern Forktail. http://bugguide.net/node/view/4983
