What does finding *Endrosis sarcitrella* exclusively in dusty reaches far from stored food or clothing imply about their diet?

Answer

Sustained entirely by accumulated lint and insect remains

The location of an infestation often reveals the primary food source supporting the population. If adult moths are observed flying in dusty, high areas far removed from typical stored resources like woolen blankets or open grain supplies, it strongly indicates that the developing larvae have been sustained solely by the accumulated organic mixture found there. This mixture consists of general building dust, shed hair, and dead insect matter, demonstrating the moth's opportunistic nature.
