Forewing colour sexually dimorphic but nearly always with a broad median band (often obscure), band broadest at costa and at its centre. Female forewing colour variable (range: dull gold, dull yellowish grey, greyish green, ochreous-brown I rosy brown) and yellowish forms with scattered dark scales; hindwing colour tending more rosy ochreous or grey than in forewing; antenna dominantly ochreous, near-filiform; ovipositor tip usually visible. Male forewing colour variable (range: ochreous-brown, rosy brown, purplish brown, grey-brown), median band colour often darker on projecting edges immediately above midline and inner line tending sinuate; hindwing usually rosy ochreous or greyish brown and transverse lines weak except towards tornus; antenna strongly bipectinate, pectinations held rather straight; abdomen strongly tufted apically.
