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.

Female Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly AdultFemale 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 (

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.

Brachycentrus appalachia (Apple Caddis) Caddisfly AdultBrachycentrus appalachia (Apple Caddis) Caddisfly Adult View 9 PicturesThe wings of this specimen were pale tan, almost white, when I collected it, and the body was of the lighter "apple green" from which this species gets its common name. Everything turned much darker by the time I got it home and under the camera.

The wings look even darker in some of these pictures because the background is black and the wings are unusually translucent. You can see that in one of the pictures where the body easily through the wings. They're really a light, translucent gray, which is still far from the pale tan of the same fly when it was freshly emerged.

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.
