Not sure what this is. Maybe baetidae, maybe not. Very small... barely 3mm. Don't know if it has hind wings or not - will have to check specimen under a microscope. Brown body. Appears to have 2 tails, but again, I need to look under magnification.

Also saw a very few small (#18-20) caddis, both dark and light. Did not capture any. I Might have seen one large mayfly spinner near dark, but didn't get close enough to confirm.

Went to the parents' house to set up the moth light! It had rained just a little tiny bit before hand -- I think that caused lots of bugs to come out.

Description

Large (size 10 or so), brown/mahogany body, clear wings, reddish eyes with stripe in middle (this seems a distinguishing characteristic of Isonychia). 2 tails. Imago. Surprised to see this genus on this river.

They are aquatic insects whose immature stage (called "naiad" or, colloquially, "nymph") usually lasts one year in fresh water. The adults...
