    Wrong color. The Salmon Flies here in Montana are a very different color.

    I saw a bug that looked similar to that, but all that was left of it was it's shell casing. Two of them were stuck to the underside of a bridge on the Foss river. They were better than 2" long They were above the high water mark. First time I ever saw a bug that big in Western Washington.

    Hi triploidjunkie-

    Was it approximately 3/4 of an inch in length, as measured from the front of its head to the end of its wings?

    Sorry about the lousy pic quality. If you're able to zoom in you can faintly see that there is quite a bit of orange in several spots on it's underside. That and it was probably around 1 3/4 of an inch long, maybe slightly longer, made me think salmonfly over stonefly.

    Here is version of your photo which has been manipulated for easier viewing:

    Actually, the resolution and focus are pretty reasonable. However, stonefly (unlike mayfly and caddisfly) adults are somewhat easier (at least for me) to recognize from a dorsal (overhead) view. I have consulted with (professional entomologist) Robert Newell regarding this stonefly, and he suspects it to be of genus Skwala.

    Thanks taxon. Big damn bug. I didn't realize skwalas got that large. This early and cold I should've known better. Don't most salmonflies hatch in much,much warmer weather?

    triploidjunkie-

    In all fairness, I wasn't able to relay its size at the time I exchanged emails with Bob. So, if your estimated length of at least 1 3/4 inches (~44 mm) is not grossly exaggerated (which is really easy to do), your stonefly would pretty much have to be a Salmonfly, as no other WA stonefly adults would exceed ~33 mm, and a Skwala would not exceed ~18 mm.

    With average temperatures, a few Salmonflies might be expected show up by the middle of April, but the vast majority would not emerge until May and June, and then trail off during the 1st half of July.

    Incidentally, before my email exchange with Bob, I had been thinking it might be (Dwarf Salmonfly) Pteronarcella regularis, but its length would been no longer than 25 mm, which is a far cry from 44 mm.

    Hi McNasty-

    Yeah, I hear you, and quite frankly, feel a bit the same way.

    I know it was over an inch and a half(the width of a 2x4). Too bad none of the streams are open yet around here. A giant stone nymph, or just a classic bitch creek, would probably wreak some havoc.

    That's a salmon fly. But an early bird for sure.

    There is at least one place where a major hatch of salmon flies occurs the first week of May, but I'm not telling where.

    Hey Taxon, quit using mm's. Most people here in the U. S. use the American way to measure things. A mm doesn't mean anything to me. LOL

    Yeah, I hear you OMJ. However, both the scientific community, and flyfishing entomology authors use millimeters to describe the length of aquatic insect bodies, which (in my opinion) is a whole lot handier than having to deal with fractions of an inch.

    Mustad 94840/94845 (straight part of hook shank, on which the body of an imitation is tied) lengths measure approximately as follows:

    #10 = 12 mm
    #12 = 10 mm
    #14 = 8 mm
    #16 = 7 mm
    #18 = 6 mm

    Hope this helps.
