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

This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and
fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

These are found in the Russian River in shallow to moderate depths of water with a good flow. They are usually found February through April. The naiads are about 16 - 20 mm in length at maturity.

Beautiful creature. But if I were small, I wouldn't want to meet one of those on a dark night under a lily pad...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

I wouldn't want to either. Minding your own business, then that labium shoots out and you're gone.

Hmmm...looks like someone was uninvited to our site. Having only read the post about the "stink bug you freaking idiots", I could tell he didn't belong here - and not only because he apparently doesn't know (expletive deleted) about insects.
The coolest dragonfly nymphs I have seen recently were a bunch of leaf-green ones with light stripes down their sides, and fairly slender bodies, taken from some emergent grass in shallow water from [REDACTED] Pond. Sadly, their color didn't last in 70% ethanol. Are there other green dragonflies out there I don't know about? These were the first and only ones I've ever seen. Perhaps next season I'll grab a few for a photo and put them up ion here for our "bugnuts" to identify.

Here is a reference for immature odonate coloration. Dragonflies Behavior and Ecology of the Odonata Philip S. Corbet, 1999, Comstock Publishing Associates,
Cornell University Press, Ithaca, NY.
It indicates that the immatures can change color to match habitat but it is a slow process occurring at the molts.
I suspect camouflage is important for lots of reasons for all insects. I doubt any insect coloration changes occur as fast as we see in things like the octopus videos. totally different structural and nervous systems.
