Backyard and Beyond

I could barely see, and barely photograph, this one on the side of a tree. I first thought it was some kind of moth.
The very long antennae forms, mostly in shade, are rather un-mothlike, though.
Turns out this is a giant casemaker caddisfly, possibly in the species Banksiola. The aquatic larvae stage given them their general name; they make protective cases of silk, plant material, even tiny bits of gravel.
