Blue-winged Olives

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.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

Is there any reason you posted three images of one picture and seven images of the other picture? I guess you wanted to make sure we saw it.

I think it might be a caddis, probably a member of the Hydropsychidae family. You can see what appear to be gills under the body and the filaments on the end of the body.

You are correct that it is a hydropsychid. And I would go with one of the Hydropsyche species.
