Rather a fine moth, inhabiting Europe, though not
found in England. It expands about two inches or
more. The fore-wings are dark brown, sometimes
suffused with a reddish tinge at the upper margin.
The hind-wings are of a greyish pearl-white colour,
veined with brown, with a brown shade fringing the
margins. The larva is greyish-brown, and feeds on the
potato-plant, where it is found during the late winter
and early spring. The average time for turning from
the larva to the moth stage is from six to eight weeks.
