    I would guess caddis larvae.

    Exactly so, good job Big E. Here is an the illustration of an Atherix pachypus larva of family Athericidae from the book, Aquatic Entomology, which was written by W. Patrick McCafferty, and illustrated by Arwin W. Provonsha:

    And, here is a photo by Tom Murray of what one looks look like as an adult:

    BTW, I had a look through some of your other pics....pretty awesome! You should post pics of them more often. One of your pics you commented that you didn't know the orientation...they have two "horns" on their posterior and a pointed anterior.

    Thanks for the help. I am surprised there is not more information about these critters out there. I frankly had never heard of them. But they are abundant and pretty meaty looking for fish food. Since they are part of Diptera I assume they go through complete metamorphosis, I am curious what kind of emergence strategy they have, crawling out or floating up, etc.

    According to this website the larvae pupate on land. So I guess I can't start telling people I am fishing the water snipe hatch :rofl: There is a good chance some would get swept up in the current during migration to the shore. Now if I can just find out when that happens I can tell people I am going to fish the water snipe migration . . .

    Yes, here is a more complete description of the watersnipe fly life cycle. The adult females deposit their fertilized eggs in a communal egg mass on tree branch overhanging stream. When the eggs hatch, the larvae drop into the water, where they live and grow for (~11) months. When the mature larvae (pre-pupae) depart their aquatic environment, they do so by crawling from the stream's edge, and pupating in the soil along the stream bank. After a few weeks of pupation, the mature pupae emerge in early summer as winged adults.

    Nope, that is a mayfly nymph to the right in the first picture. Here is a picture of a stonefly.

    I concur, in the first photo that is a mayfly nymph and by the looks of it a crawler mayfly, as opposed to a clinger, burrower or a swimmer mayfly nymph.

    Right, you are, Flyfishdude. It's the Ephemerellid, Drunella grandis, which has a common name of Western Green Drake.
