Sorry sciguy - keyed out and cross referenced with 3 separate guides - 2 toes, 2 tails. It is Chloroperlidae, which is very common in the particular stream I sampled. I've been a trained rapid bioassessment person for 15 years.
I fly fish so I see a lot of larvae and I know that's not a stonefly judging by the green I would say that might be a caddis larvae
