Fall Webworm

Ned picked out this lone critter on a Goodding's willow in the riparian area above the dam. In the shade, no less. We (Carol T, Ned, and I) were really hoping it was a bag worm moth, but Bug Eric identified it as a Fall Webworm moth. The larvae of the Fall Webworm make the big webbed nests in the willows in the summer and fall.
