General comments
Widespread, but surprisingly not ubiquitous.

The White-shouldered House Moth is more or less omnivorous on dead animal and plant matter. For many years, the wicker basket that I keep in my bathroom to house dirty linen was infested about its base with the larvae of this moth. In spite of many attempts to eradicate it, the moth continued to thrive and during 2003 I recorded five successive generations. There is also a resident population inside my Land Rover! The species is often synanthropic, but is also well able to thrive in more natural locations (e.g., I have reared it from birds' nests). The reason for the blank areas in the distribution map are currently obscure.
