This moth has a grey or light-grey ground colour (sometimes buff-coloured) with distinct dark grey patches on forewing. The thorax is dark and the abdomen is usually white. The central cross-band usually fades towards the trailing edge. The cross-band varies in thickness and sometimes is just a small blotch at the leading edge (f. costovata). A melanic form (f. thules) is sometimes so dark that the central band is indistinct from the ground colour.
Pupates in loose soil.
Gardens, allotments and rough ground in urban areas. Also woodland and open coastal areas.
There are no records in the system yet in Bulgaria.
