Hindwings are grayish brown with yellowish-orange apical shading. Males have a forewing costal fold. Some phenotypes of Archips rosana can appear similar to several other Archips species, including: Archips betulana, Archips crataegana, Archips grisea, Archips oporana, Archips podana, and Archips xylosteana. Forewing markings in most A. rosana individuals are more subdued than in these other species. Larval Morphology Last instar larvae are 15-20 mm in length. The abdomen is dull pale green to dark olive green with pale pinacula. The head is reddish brown to dark brown. The greenish-brown prothoracic shield is shaded posteriorly with dark brown to black; the degree of shading varies. Thoracic legs are brown to black. Larvae of A. rosana are similar to those of Adoxophyes orana, Archips podana, and Choristoneura rosaceana. Biology Archips rosana completes one generation per year. Adults are present in late June to August. The life cycle of A. rosana is similar to that of Archips argyrospila. Females lay eggs in masses of approximately 60 individual eggs on woody parts of the host plant. Eggs overwinter and larvae hatch the following spring. Larvae feed on leaves, flowers, and small fruits, rolling leaves in later instars. Pupation occurs in the final larval feeding site. Host plants Archips rosana is a pest of fruit trees and other Rosaceae in Europe and the Pacific Northwest. Larvae are polyphagous, feeding on members of more than 15 plant families. Chapman and Lienk (1972) speculate that primary hosts are apple, currant, hawthorn, pear, and privet.

It was introduced into North America prior to 1890 where it is currently present in the Northeast and Pacific Northwest. References Bradley, J. D., W. G. Tremewan and A. Smith. 1973.
