Moved from Stoneflies.

Going strictly by distribution, this almost has to be Pteronarcys prot*eus. This is a female. The key character is on the underside of the terminal abdominal segments. A good clear photo of that region would probably make a species ID possible.


No problem
Always glad to help.
