from Lloyd Gonzales: "Looks like Hesperoperla pacifica to me"
"I'm not sure what the size is measuring, but if it approached 40mm in length to wingtip, it was probably a female."

Moved from ID Request.

 
Hesperoperla pacifica
Yes, the size measurment was based on length to wingtips. Excellent! Thank you and Lloyd!

That's the
Deschutes River, btw.
At 40-45mm it's probably a Perlid - Calineuria maybe?

nice -- will show it to Lloyd
for the future: to have your images noticed by the experts and get IDs faster, post all caddis-, stone-, and mayfly pix to the respective order pages rather than to ID Request
