Technical description and variation
A. strigosa F. (= favillacea Esp.) (3e). Forewing pale grey, tinged with ochreous; base of inner margin yellow: reniform stigma externally yellowish; a broken black streak along submedian fold. Larva velvety green, with broad redbrown dorsal band; hairs scattered and fine; dorsum humped on segment 12; like the larva of Cerura , which it resembles superficially in colour and ornamentation, it changes from green to dull purplish before spinning up; fullfed in autumn; on hawthorn, which is its only foodplant in Britain, though continental writers give sloe and Rhamnus. — ab. bryophiloides Horm. (— casparii Steinert) (3 e) is a smaller form with the forewings wholly dark grey. -- Japanese specimens are considerably larger than European and much darker; the stigmata more strongly indicated, and the black dashes thicker; they may be distinguished as adaucta subsp. nov. (3e).[2]The wingspan is approximately 32 mm.
Biology
The adults fly in June and July.[1] They are attracted to light.
The larvae feed mainly on hawthorn and sometimes blackthorn.
Notes
