Author: Walker, 1855
forewing length 1.5 - 2.1 cm (1)
Adult - yellow tan or pale tan with thin wavey lines. Easily distinguished by their sharp falcate forewing apexes (1)

Larvae - green with mottled brown, purple and black on the dorsum. There are paired prominent dorsal bumps or verrucae on the second thoratic through second abdominal segments. The head is whitish with two brown purple bands. The last abdominal segment is acuminate with a short dorsal horn and is held in an elevated position while at rest (1)
widespread across temperate North America from southern Alaska east across Canada to Newfoundland and south to northern California, Colorado, Texas, and the southeast (1)
Adults fly from May to August (mainly June to July) (1)
larva feed on alders, Alnus rubra and Alnus viridis var. sinuata (Betulaceae) (1)
Life Cycle
larvae live in silk-lined shelters on leaves that have the edged folded up. When disturbed they are said to make a faint tapping noise that may serve to space out competing individuals. Pupation is within the folded leaf in a tough, pale brown cocoon (1)
