Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington

This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

This specimens shows that the name "green rockworm" doesn't quite fit all Rhyacophila larvae, even though it does fit the majority. This is actually the first of their larvae that I've found in a different color. I'm not sure if it's because of the species or because this is a young one, but I have found equally small green larvae, so I'm guessing it's the species.
