Posts: 287We have 2 stoneflies hatch now in PA. One I call the snow-stone because it's easily seen walking the snow banks, and is very tiny. I believe it's entomological name is Taeniopterygidae?
The other one is larger like a size 14 or 16. Is it the Early brownstone? What size is the nymph and adult?

The small stoneflies you are seeing on the snow are likely Capniidae. I don't think I've ever caught a fish on an imitation of that fly. The larger ones are the Taeniopterygidae. Now those are a different story, and often account for some decent dry fly fishing. I'd say they are around a size 16.They often look bigger because their wings extend a little past the abdomen. But I pretty much tie all my adult imitations on a size 16.
