There are 14 named species of Virbia in America north of Mexico. (1)
Wingspan about 24 mm.
Easily confused with Virbia aurantiaca. The subterminal hindwing band of V. aurantiaca is solid, whereas the subterminal area of V. ferruginosa has a series of blotches and spots, not a solid band, according to this revision of the genus. This presumably applies to males only, since the revision shows images of females of both species with black splotches rather than a solid band on the hindwings. There are also forms of V. ferruginosa that lack the black markings on the hindwings altogether and could be confused with V. immaculata, but V. immaculata is smaller and generally emerges in June and August in the Northeast (sometimes very late July), while V. ferruginosa emerges mostly in July (sometimes very late June)
Across Canada west to B.C. Not known to occur in the western U.S. [cite:1187786]

Late June to July [cite:1187786]
Larvae have been reared on Taraxacum (dandelion)
Some Virbia species are almost indistinguishable by their geni-talic characteristics; in addition, a variety of wing color patterns occur, rendering species determination difficult. (1)
The identification of the western species in this complex, V. aurantiaca (Huebner), V. fragilis (Strecker), and V. ferruginosa (Walker) is not clearcut, and the taxonomy is in need of revision. [cite:1187786]
Formerly placed in the genus Holomelina [cite:1187786]
