Brachycentrus appalachia (Apple Caddis) Caddisfly AdultBrachycentrus appalachia (Apple Caddis) Caddisfly Adult View 13 PicturesI captured this specimen in the same color as this photograph, during its egg-laying flight. The emergers are much lighter.

Neophylax (Autumn Mottled Sedges) Caddisfly LarvaNeophylax (Autumn Mottled Sedges) Caddisfly Larva View 11 PicturesI haven't really had time to ID this one; I'm just tentatively guessing based on the case that it's in Glossosomatidae.

Rhyacophila fuscula (Green Sedge) Caddisfly LarvaRhyacophila fuscula (Green Sedge) Caddisfly Larva View 11 PicturesI collected this larva and several like it from the same stream and on the same day as this pupa. I suspect they're the same species.

Rhyacophila (Green Sedges) Caddisfly PupaRhyacophila (Green Sedges) Caddisfly Pupa View 11 PicturesI collected this pupa and several like it from the same stream and on the same day as this larva. I suspect they're the same species. Every pupa I collected was in a brown casing like the one shown in one of the pictures below. I cut this pupa out of its case after a picture so you can see more details. It is close to but not fully developed.

Brachycentrus (Grannoms) Caddisfly PupaBrachycentrus (Grannoms) Caddisfly Pupa View 10 PicturesThe green blob contained in this case is a pupa in the early stages of transformation from larva to the final stage we generally picture and imitate. This specimen and several like it were fixed to a rock I picked up, and each one had the front of its case sealed off, protecting the helpless pupa from predation. It's neat to see the insect part-way through such a radical transformation.

It was very hard to extract this thing from its case, so there's a bit of extra goo near the head from where I accidentally punctured it.

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.
