Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Dorsal view of a Pycnopsyche guttifera (Limnephilidae) (Great Autumn Brown Sedge) Caddisfly Larva from the Yakima River in Washington

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

From the anal gills and the markings, this appears to be Agnetina--probably capitata.

In case you didn't know, there is an excellent color drawing of Perla capitata, as the species was formerly known, which you can compare to your excellent color photographs. It serves as the frontispiece to Peter W. Claassen's Plecoptera Nymnphs of America North of Mexico (Springfield, Ill: The Thomas Say Foundation, 1931).On page 45 Claassen notes: "...easily recognized by the two dark transverse bands across the head, the two dark trabnsverse bands on the femeora, the presence of caudal gills and the yellow and dark banded abdomen." As with you, Claasssen was at Cornell.
