This is a small moth, about one to one and a half inches
in expanse, and found throughout the greater part of
Europe, Northern and Western Asia, and North Africa.
It frequents high ground in the spring and summer,
living in rough places and in clover-fields. The fore-wings
are of light olive-brown shade, with dark markings
across them. The hind-wings are dark olive-brown,
fringed with yellow, and having two large yellow uneven
spots about the centre, with a similar one on the brown
margin. The body is stout, the antennæ long and fine.
The larva is green or rust-colour, with white lines on
the back and sides.
