It is found in North America, including south-eastern Canada and the north-eastern United States.

The forewings are snow white, sprinkled with ferruginous-brown scales, especially on the outer half of the costa.

There is a dark-brown fine streak on the outer half of the costa of the second lobe extending through the fringe under the apex.

When full-grown, the larvae are pale pea green, with a paler head and a dorsal stripe consisting of three white lines.

Pupation takes place in a light green pupa, although some have a reddish stripe along the dorsal part of the abdomen.
