Appearance
The forewing is yellowish cream and has a large dark brown blotch that extends diagonally upward from the inner margin near the anal angle. Between the large blotch and the thorax, there may be other brown blotches and shading because it varies from each moth in the species. It has a wingspan that ranges from 18 to 25 millimeters. Adults are on wing from May to July.References:
