Rhyacophila carolina (Green Sedge) Caddisfly LarvaRhyacophila carolina (Green Sedge) Caddisfly Larva View 8 PicturesThis 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.

Neophylax (Autumn Mottled Sedges) Caddisfly LarvaNeophylax (Autumn Mottled Sedges) Caddisfly Larva View 7 PicturesThe size of the head compared to the body in this larva is surprising, and I think this means it's a fairly early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) of something which is going to get a lot bigger, but I'm not sure.
