(1973) lists eight forms as occuring in the United Kingdom. Powell (1964) describes three distinct phenotypes found in western North America: 1) forewing white on inner half with a dark dorsal triangle, outer half dark-purplish; 2) forewing divided into white basal and blue-black or purplish distal area; 3) and forewing ground color tan with a basal dorsal triangle and purplish outer costal triangle. Males lack a forewing costal fold. Acleris variegana may appear similar to certain forms of other Acleris species, including A. keiferi, A. maculidorsana, and A. robinsoniana in North America and A. permutana in Europe. A genitalic dissection can be used to confirm identity. Larval Morphology Larvae are yellowish or light green. The head is brown and the prothoracic shield is concolorous with the abdomen. Legs are brown or pale. Most individuals exhibit a black spot located laterally on the head and a dark posterolateral mark on each side of the prothoracic shield. Biology Acleris variegana completes two generations per year in North America. Adults fly from April to July and again from August to November. Overwintering occurs as a second generation adult. Eggs are laid singly or in small batches on leaves of the host plant. Early instar larvae tie together two leaves and skeletonize them from the inside; later instars consume the entire leaf. Pupation occurs in the larval shelter or among dead leaves on the ground. Host plants Larvae have been recorded feeding on a variety of host plants, primarily those in the family Rosaceae.

It was first reported from North America in the early 1900's where it is present on the East and West Coasts. References Bradley, J. D., W. G. Tremewan and A. Smith. 1973.
