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.
Collected June 5, 2005 from the Long Lake Branch of the White River in Wisconsin

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 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.

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.

Male Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly AdultMale Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult View 6 PicturesThis caddis species was dancing high over the stream, spaced a foot or two apart across most of its width, very much like Ephemera mayfly spinners but with more side-to-side motion mixed in. There were more than enough to get the trout interested, but I wasn't able to stick around until they fell on the water (if they did at all).
Collected May 28, 2007 from Mystery Creek #42 in Pennsylvania
