FWL: 6.5-8.5 mm
Forewings are bright yellow with variable orange to orange-brown markings and reticulations. There are often two conspicuous orange fasciae running from costa to dorum, but these may be obscured by the reticulated pattern in some individuals. The male hindwings are dark brown, while the female hindwings are golden brown. Males lack a forewing costal fold.
Adults of Argyrotaenia quercifoliana may appear similar to those of A. quadrifasciana. The two species can be distinguished by forewing color: bright yellow in A. quadrifasciana versus pale yellow in A. quercifoliana. In addition, the hindwings of A. quercifoliana are white, while those of A. quadrifasciana are dark brown or golden brown.
Last instar larvae are 12-17 mm in length. The abdomen, head, and prothoracic shield are yellowish green and unmarked.
The green unmarked larva can be confused with the larva of many other tortricids, including other species of Argyrotaenia, Epiphyas postvittana, and Choristoneura rosaceana.
Argyrotaenia quadrifasciana completes one generation per year. Adults are present in late June and July.
Females deposit eggs in masses that contain approximately 50 individual eggs on the upper surface of leaves of the host plant. Early instar larvae skeletonize the underside of a leaf near the midrib under a patch of silk. Third instar larvae leave the feeding site and construct a hibernaculum in the crotches of twigs and bark crevices, where they overwinter until the following spring. In the spring, larvae leave the hibernaculum and construct a nest by webbing together terminal shoot growth, where they feed inside on shoots and buds. Pupation occurs in the final larval feeding site.
Larvae of Argyrotaenia quadrifasciana have only been recorded feeding on plants in the Rosaceae.

Argyrotaenia quadrifasciana is distributed in eastern North America, where it is more common in the Northeast and southern Canada.
