Hydropsyche (Spotted Sedges) Caddisfly AdultHydropsyche (Spotted Sedges) Caddisfly Adult View 11 PicturesI haven't keyed this specimen out, but I am instead placing it in Hydropsyche based on the striking visual similarity to this one, which I did key out.

Female Brachycentrus americanus (American Grannom) Caddisfly AdultFemale Brachycentrus americanus (American Grannom) Caddisfly Adult View 1 PicturesSize 11 mm. Prior to this photo the specimen dropped its large egg mass that was a very dark (almost black) olive sphere almost twice the diameter of the abdomen. Notice the abdomen visible through the wings is both thickened and shortened post egg drop.

Male Cheumatopsyche (Little Sister Sedges) Caddisfly AdultMale Cheumatopsyche (Little Sister Sedges) Caddisfly Adult View 12 PicturesI didn't identify this one directly, but I eventually identified one of several I collected from the same swarms that appeared to be of the same species. (I lost track of which specimen was which in storage.) The microscope pictures come from one of these specimen, not necessarily the same specimen as the DSLR pictures. They key to Cheumatopsyche, and the hind wing venation (Venation: The pattern in which the veins on the wings of an insect are arranged. It is usually one of the most useful identifying characteristics.) that separates them from Hydropsyche is pretty clear in the attached picture as well as another specimen I checked under the scope.

This specimen was one of tens of thousands we saw on a July 1st evening on the Madison, beginning with big swarms around every vehicle and tree at the Eight Mile Ford access point and continuing all up and down the river bank. We somehow didn't catch any trout, perhaps because they were stuffed with pupae from when these things emerged. Or maybe we just weren't fishing well. Either way, this one represents a major hatch there.

I somehow forgot to photograph this important specimen against the hooks size chart, but fortunately I preserved a few. The body length is about 6 mm, and total length from head to wingtip is 9 mm.

Dolophilodes (Medium Evening Sedges) Caddisfly LarvaDolophilodes (Medium Evening Sedges) Caddisfly Larva View 9 PicturesI think this larva best fits Dolophilodes, in which the anterior (Anterior: Toward the front of an organism's body. The phrase "anterior to" means "in front of.") margin of the frontoclypeus is supposed to be "slightly asymmetrical." I can't confidently make out the asymmetry, but the other genera are supposed to have either greater asymmetry or a symmetrical, but convex, shape, whereas this one is clearly concave.

Based on distribution records, the species should be either aequalis, dorcus, or pallidipes, but I can't find any source to distinguish between them.
