Yorkshire Status: Common and widespread resident.

In 1883, Porritt described Mouse Moth as "common probably everywhere" and this is probably true today as this is a common moth across the county, especially in lowland habitats. Nationally however many people are becoming rather worried as it has been disappearing from many of its old haunts, particularly in the west of the country. There is no cause for alarm however (yet) in Yorkshire, though large catches of 20 or 30 moths are not as common as they used to be. It is well named, scuttling around the trap and the egg tray if you are trying to pot it, and showing reluctance to fly.

Sutton & Beaumont, 1989: Frequent to common in all five vice-counties. This species is known for its habit of congregating in crevices in buildings and old trees and scuttling away rather than flying when disturbed, hence the English name.
