The Specimen

Isoperla (Yellow Sallies) Stonefly AdultIsoperla (Yellow Sallies) Stonefly AdultView 10 PicturesSeveral 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.

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.

Jason-

Likely Isoperla, perhaps I. bilineata.

Ok, I'll move it over to Isoperla for now. According to Swisher and Richards, bilineata is an olive and brown species, so I don't think it's that one. This one is distinctly yellow; the brown accents are exaggerated a bit in the photo processing because it just looks so cool.
