General Description

fourni par University of Alberta Museums
"Easy to recognize by its size and distinctive forewing pattern. The forewing is white to light grey with variable brown shading in the lower median and basal areas. A large black triangle is present at the middle of the costa that is interrupted by a narrow line just before the postmedian area. The head and thorax is concolorous with the forewing and the latter has small paired tufts near the wing bases. The larva is completely greenish except for a small dark spot amongst the eyes, faint dark green speckling on the anal shield, and rarely dark edging to the thoracic shield (Chapman & Lienk 1971, MacKay 1962)."

Life Cycle

fourni par University of Alberta Museums
Eggs are laid in batches of 20 to 273 on leaves and twigs and are initially green but later turn yellowish-orange. First instar larvae suspend themselves on silken lines and occasionally get dispersed by wind to other plants. Early instars skeletonize the leaves, and the later instars either roll the leaves, silk several together, or silk a leaf to a fruit and feed on both. The larva is active from June until September and it overwinters as a pupa. (Chapman & Lienk 1971)
