Rhyacophila mainensis (Green Sedge) Caddisfly LarvaRhyacophila mainensis (Green Sedge) Caddisfly Larva View 10 PicturesThis is the first Rhyacophila larva I've seen with this striking black banded appearance. I caught several larvae of this species in a fast riffle in a mid-sized trout stream.

Cheumatopsyche (Little Sister Sedges) Caddisfly PupaCheumatopsyche (Little Sister Sedges) Caddisfly Pupa View 3 PicturesI was surprised how bright green this pupa is. It's chartreuse. After collecting it, I experimented with melting down chartreuse jigs and making little translucent rubber caddis abdomens on my flies. They looked good, and the trout liked them, but they weren't very durable at all. This specimen is recently deceased in the photographs.

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.

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.
