Rhyacophila 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.

Phryganeidae Caddisfly Larva
View 5 PicturesThis "specimen" is actually two caddis larvae fighting each other over a case. The case is a hollow tube; one larva would go in the back end, presumably bite the other, and chase it out. The invader crawled forward into the case while the other one fled, and then it went around to the back and bit the first one. They did this several times, and I recorded it on video.

Neophylax (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.

Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult
View 6 PicturesThis is a really strange specimen. I would guess it's one of the dry caddis pupa that scoots across the surface of the water as a pupa rather than emerging right away. Its "wing pads (Wing pad: A protrusion from the thorax of an insect nymph which holds the developing wings. Black wing pads usually indicate that the nymph is nearly ready to emerge into an adult.)" sure don't look right, though. Maybe they're deformed and that's why I was able to find this one as a pupa in the first place. It also looks like it might be a caddis adult missing its wings, but since I found three of them, that kind of rules out such an anomalous maiming.
I found this one and one other on a midstream rock. The previous day, I caught a similar creature kicking around on the water's surface.
This one died and shriveled a little bit before I could photograph it, but it's basically in its original shape.

Rhyacophila 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.
