Dorsal view of a Limnephilidae (Giant Sedges) Caddisfly Larva from the Yakima River in Washington

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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.

Hi Jason,

This is a chloroperlid. Among other traits, the tiny, asymmetrically inserted terminal segment of the maxillary palp is distinctive for this family.

The revamped site is cool. Nice work.

Best,
Lloyd
