Distribution


Imago

Wingspan 16–25 mm. Forewings of both sexes are light brown to pale yellow with brown to dark-brown markings. Males are more variable than females, although in most males the basal half of the forewing is lightly marked, the median fascia is well defined, and there is a dark mark on the costa distal to the median fascia.
The female forewing color is more uniform, with a poorly defined median fascia and an overall mottled or speckled appearance. Most females have a dark mark on the dorsum of each forewing and two dark spots on the posterior of the thorax.

Bionomics

Young larvae feed on the undersides of leaves within a silk chamber. Older larvae may fold individual leaves, create a nest of several leaves webbed together, or web leaves to fruit and feed on the surface of the fruit. Larvae on deciduous trees and shrubs feed as long as leaves remain on the food plant and then fall down to the ground, where they may feed on understory vegetation or survive in leaf litter.
This species can be a pest species in orchards. The adults come to light.
