Technical description and variation
Шаблон:Entomology glossary hatnote 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).[1] The wingspan is approximately 32 mm. The caterpillars appear in two colour variants, either green with a brown back or completely brown. They have few short, fine hairs. The slender pupa is light brown colored. The cremaster is short and equipped with thorns.
