Agrochola lota

Forewing grey brown or leaden grey, often with a reddish tinge; inner and outer lines double, conversely lunulate-dentate, but rarely visible; a thick darkmedian shade; stigmata grey, with pinkish annuli edged with rufous, the lower half of reniform black; submarginal line nearly straight but angled on vein 7, pale with rufous inward edging; hindwing dark grey, with cellspot and submarginal cloud showing darker; the reddish examples in which the grey tints have entirely given place to rufous, form the ab. rufa Tutt ; in rare cases the grey is darkened into black; this is ab. suffusa Tutt from Ireland; an equally rare form from England, in which the ground colour is whitish grey is pallida Tutt; in a form from Amasia, ab. subdita ab.nov.[Warren] the grey ground is duller and paler in both wings, and the black in lower lobe of reniform is much reduced.[1]

This moth flies from September to October and is attracted to light.

The young caterpillars feed on the catkins of sallow and willow (Salix),[2] progressing to eating leaves when mature. They hide in spun leaves by day and feed at night.
