The other evening while fishing the Savage River in Western MD, I noticed some flying insects that I had never seen before. The were very fast fliers and, despite my best efforts, I could not collect any in my cap for closer observation. They flew approx. 6 inches above the water in groups of 6 to 8 and they flew in what appeared to be a figure-8 type pattern and, like I said, they were very quick. From what I could tell, they were about the size of a large mosquito or crane fly. Anyone have an idea of what this insect might be?

Scott,

If they were dark in color and had longish antennae, my guess would be Black Dancer Caddisflies (Mystacides). Another possibility would be some type of aquatic beetle adults. Those would be the most likely candidates that I have personally seen behaving thusly.
Best regards,

I'm going to guess a fly -a dipterid, but not a midge. We have them (I've not ID'd them) and they do as described.
