What key diagnostic feature gives the White-shouldered House Moth its common name?
Answer
A distinct white patch near the leading edge of the wing base
The common name of the moth is derived directly from a visible anatomical characteristic used for rapid identification. This key feature is a prominent white marking, often described as a patch or shoulder marking, located close to the leading edge where the forewing attaches near the body. While the overall wings are pale grey speckled with dark scales, this specific white feature is the most reliable visual cue mentioned for confirming the identity of *E. sarcitrella*.
