30 -35 mm.


Distinguished from its congeners by the conspicuously barred cilia of fore- and hindwingThis moth gets its common name from the variegated pattern of the forewing, in various shades of black, brown and white, which look rather like a map (although there are plainer forms). Unlike most hepialids, the pattern is rather similar in both sexes although the female is usually rather larger with a wingspan of up to 50 mm.
