    Thanks to Curt, I was able to find it. It appears to be a millipede, probably Harpaphe haydeniana.

    Was it in the water? And alive? If so, it doesn't sound like a centipede/millipede to me??

    Sorry for the delay in getting back to this. Had my head in painting the inlaws house. Yes, it was in the water crawling around on the rocks on the bottom of the creek. I was looking in the water and saw it moving slowly from one rock to another. I got it out and then took pictures of it. I returned it to the creek after we had took pictures of it. Maybe I put him back where he did not belong.

    I'm thinking alderfly larva... doesn't look like a centepede or millipede to me (and the casing in interesting. Was the casing attached? Could have been eating a caddifly larva...).

    What appears to be a casing is a piece of wood the insect was hanging onto when I pulled it out of the water. The bugs outer case is the green and yellow side, and the bottom or leg side is the darker side.

    Were the legs consistent (size shape) all the way down? It looks like the upper portion as the real legs, and the lower are shorter appendages and not the same jointed legs. Under water would indicate that it was not a centipede or millipede. Some beetle larva will go under water for a meal...

    Have you looked up alderfly larva yet? Do a google search, then click "images".

    Forgot to add...

    If it had large jaws, it could also be a dobson fly larva (hellgrammite)

    Nice images. I was wondering if perhaps it was a hellgramite. Interested in seeing what the final verdict is on this one so I can finalize the pattern... is it a variegated filoplume san juan worm? or... ?

    Jim,

    By "final verdict", did you mean the correct identification, or just the last word? :thumb:
