Salmonflies
Pteronarcys californica
The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

I am not 100% sure, but I think it is a Chloroperlid. If not, it is a Perlodid (I don't think it is though). Do you have pictures of outstretched wings? Do you know the size?

It's been a long time, but I think this one was pretty small. You're probably right about Chloroperlidae.

Looks like Perlodidae to me. In the ventral view, notice the metathoracic sternacostal sutures that extend laterally from the anterior end of furcal pits.

Thanks Motacilla. I've moved it to Perlodidae.
