Assorted Caddis Pupae

I'm just going to include these together, as I haven't been able to tell what they are all yet --

(body length approx. 4 mm)

If I were to make a completely uneducated guess, I'd say that these are the same kind of bug (more than likely glossoma), but the darker one on the right (in the middle?) is closer to hatching. In real life they weave silk coccoons attached under rocks or similar structure, like the image on the right.

(body length approx. 8 mm)

If I were to make another uneducated guess, I'd say that these are Hydropsychidae.

Both of these pupae were found in the McKenzie in late spring (June). -----------------------------------------
