Larvae feed on spider webs, hair, wool, silk, and organic debris such as dead insects.

Behavior Patterns

The larva constructs a cigar-shaped or pumpkinseed-shaped case made of silk, sand, and dust which it carries as it crawls. It can poke its head out from either end of the case to feed or move.
