What visual characteristic gives the White-shouldered House Moth its common name?
Answer
A noticeable pale or white patch located near the base of the forewings.
The common name directly relates to a striking physical feature observable on the adult insect. This moth possesses a distinct area, often referred to as the shoulder area, located near the beginning section of its forewings, which appears notably pale or white in contrast to the rest of the wing surface. This specific pale marking is responsible for the descriptive part of its common name, distinguishing it visually from many other small, drab moths encountered indoors.
