I was teaching some orders of aquatic insects along Little River in Van Damme state park (redwood forest; about 1 mile inland from ocean ; Mendocino County) And we saw this black insect. I am embarrassed that I couldn’t even figure out the order. The wings did not look like they had scales.

We wish your photo was more detailed. We believe this to be a Caddisfly, Order Trichoptera. Renowned lepidopterist and Mt. Washington neighbor Julian Donahue just confirmed our identification. Here is what he has to say: “Nice website! I’ve actually been there before, and had already bookmarked it! I just never knew that you were a neighbor. And you’re correct about the caddisfly, although I can’t tell you what family it is.”
