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

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

Ok I was going through some old photos and found these pics of a green drake collected on the main stem of the Delaware River lust below Hancock.I'm guessing it was just about ready to molt judging from its color but I figured I'd post it to see what you all thought. The blue color on the thorax is an artifact I believe. IThe brown drake was on the same leaf. Nice time to be there!

Wow, I agree with Jason. I don't think I've ever seen an image of a drake so dark. Excepting a few cells in the wings, it looks like a black & white photo... Mostly black.:)

The white balance on a camera can do funny things when you're shooting against a colored background like that green foam.

Jason...Or when, due to a "little gray" ;) in the beard, it completely washes out and I end up looking like Santa Claus...:)

Well except for the blue on the thorax, the color is right on. if you notice the brown drake is normal color.
