Found this nymph on my waders after fishing Little Sandy Creek. It was large -- 1/2 to 3/4 of an inch in length. My guess was a green drake nymph because of its size and 3 tails. Any PAFF entomologists know? Thanks.
I agree MB. No doubt. Green Drake nymphs are burrowers with a long abdomen and furry looking gills. Rarely found on rocks like the clingers and they emerge from silty areas of the stream.
