Pycnopsyche guttifera (Great Autumn Brown Sedge) Caddisfly Larva Pycnopsyche guttifera (Great Autumn Brown Sedge) Caddisfly Larva

Dorsal view of a Pycnopsyche guttifera (Limnephilidae) (Great Autumn Brown Sedge) Caddisfly Larva from the Yakima River in Washington

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I identified this damselfly naiad to genus using Merritt, Cummins and Berg (2008). As far as I can tell only one species, H. americana is known to occur in California out of the four, possibly five species that are recorded for the United States. The naiads are most commonly found in areas of calm water on floating vegetation.
A common naiad to find in the Russian River. I've included several pictures since they vary quite a bit in coloration.

Gorgeous photos. Your contributions here are making me realize how many different food forms that trout may have available to them, as well as alerting me to many unfamiliar critters. It helps keep my fishing imagination alive over the winter. Thanks.

Louis - Yeah, no wonder the trout can be so picky, they've got a smorgasbord at their fin-tips. Always amazing how many different types of protein packages are in the river for them.
