Description
 
 

Maple-basswood leafroller moth is a small sparganothid leafroller moth. It occurs in the United States and southern Canada east of the Great Plains. Larvae feed on leaves, mostly on basswood and maple trees, but also on apple and other hardwood trees. Adults are found from May to September in deciduous woodlands.

Adults are to ½ (10 to 13 mm) in length and have a to 1 (23 to 28 mm) wingspan.

The forewings of the male are pale yellow or bright yellow, rarely white, with orangish-brown scales forming lines and patches. There is usually an oblique line beginning at the leading edge (costal margin) one-third of the distance between the base and the wingtip, and extending to the inner margin at the middle. The line is often fragmented, usually incomplete, sometimes entirely absent. When complete it forms a broad V shape when joined with the opposite wing. There is also usually a patch at the costal margin two-thirds of the distance between the base and the wingtip, and a horizontal line extending from the patch toward, but not reaching, the inner margin.

The forewings of the female are usually white, sometimes pale yellow, and usually have few or no markings.

The final stage (instar) caterpillar is 1 (25 mm) long, with a green or yellowish-green body and a mottled brown and reddish-brown head.
