Isoperla (Stripetails and Yellow Stones) Stonefly Adult Pictures

 Several stoneflies of this species were flying around a small stream last night. I tied on a brown drake imitation of about the right size/color to approximate these stones, and was rewarded with a hard-fighting 17-inch brown trout.

This stonefly was collected from Cayuta Creek on July 7th, 2006 and added to Troutnut.com on July 8th, 2006.

I haven't had time to look through my stonefly keys yet. It's a pretty small yellow fly, so I'm guessing Chloroperlidae, though I have no real reason to rule out Perlodidae.

I've saved it in alcohol to key out under a microscope at some later date, but it'll be a while before I have time.
