Status
Adults of the lesser yellow underwing moth have pale brown camouflaged forewings and bright yellow-orange hindwings with hooked, dark border markings.
They mainly fly from July to September, aestivation may account for the dip in numbers in the middle of August.

The smooth greyish caterpillars appear from September/October, hibernate and then reappear between April and June, and they have darker flecked markings. This species is common and widely distributed.
