Hydropsychidae Caddisfly LarvaHydropsychidae Caddisfly Larva View 5 PicturesThis is one of the most vividly green Hydropsychidae larvae I've caught.
Collected May 6, 2007 from Mongaup Creek in New York
Added to Troutnut.com by Troutnut on May 18, 2007
Leptoceridae Caddisfly AdultLeptoceridae Caddisfly Adult View 17 PicturesThis specimen keyed easily to Leptoceridae, but I hit a bit of a dead end in the genus key, because I can't seem to find the cross-veins in the wings that are supposed to help narrow it down. I took pictures of all the relevant features under the microscope; maybe somebody with more experience with the family can help.
Collected July 31, 2020 from the Henry's Fork of the Snake River in Idaho

Brachycentrus americanus (American Grannom) Caddisfly LarvaBrachycentrus americanus (American Grannom) Caddisfly Larva View 13 PicturesBoth the genus ID (Merritt & Cummins) and species ID (Flint 1984) are pretty confident for this larva, a nice example of a common western caddisfly. It was by far the most abundant insect in my kicknet sample on this trip, and many of the rocks in the fast riffle where I sampled had dozens of these larvae clinging on.

Female Hydropsyche (Spotted Sedges) Caddisfly AdultFemale Hydropsyche (Spotted Sedges) Caddisfly Adult View 7 PicturesThis species was really common along the Henry's Fork at the end of July. I photographed it along with a male that appears to be the same species, and another male of the same genus but a seemingly different, less common (on this day) species.

Mystacides sepulchralis (Black Dancer) Caddisfly AdultMystacides sepulchralis (Black Dancer) Caddisfly Adult View 3 PicturesI captured this small caddisfly from one of many dense mating swarms under overhanging alder trees in a slow stretch of the river. There were localized rises of trout under the swarms.

Rhyacophila (Green Sedges) Caddisfly PupaRhyacophila (Green Sedges) Caddisfly Pupa View 2 PicturesEven though I already have pictures of a Rhyacophila pupa in its cocoon, I took this one and then tried to keep the pupa alive, hoping to photograph it in several stages of development. That didn't work out; it seems to have died without changing much. Oh well.
