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.

There were enough of these flitting around in the evening to keep the fish looking up. Anglers can easily confuse these with Dicosmoecus species (October Caddis) at this time of year, but their wings are quite different and they like gentler flows.
