Observation notes: This is a larva of the infestation that i have been dealing with. The larvae do not carry a case (as in case making clothes moth) but rather use webbed tubbing. The larvae feed on feathers. Adults are small white winged moths that make for dark crevices when exposed to light. Larva here is about quarter inch, reddish orange head and is in position in a webbed tube wrapped in brown paper towel that was used to prepare museum specimens.
