Dasychira dorsipennataBarnes & McDunnough, 1919
Olene dorsipennata Barnes & McDunnough, 1919 (1)
Barnes & McDunnough (1919) original description as Olene dorsipennata is available online.(1)

Adult: Paler than obliquata, with less of the brown shading in the basal and postmedial areas of the forewing, and a less dentate AM line. It is also usually paler and better-marked than vagans, with a less regular PM line. It is larger, paler, and grayer than plagiata. Adults apparently never have a black bar on the forewing.

Larva: The last instar larva is distinctive for the region in which it occurs. Only those of the more southern tephra and kerrvillei may be confused. Head and integument of body very dark; prothoracic plate light brown; dorsal glands red; two long, black hair pencils anteriorly and three posteriorly; the usual rosette-like cluster of white plumed hair arising from brown subdorsal verrucae; hair otherwise gray, including dorsal tufts on abdominal segments 1-4, except for a few long, lateral black hairs very narrowly plumose or merely barbed, one or two arising from each subspiracular verruca. All other species on deciduous trees in the Northeast, occurring where they are likely to be sympatric with dorsipennata, lack the posterior dorsal hair pencil.
Occurs from Nova Scotia, Maine, and southern Quebec west through Ontario, Wisconsin and Minnesota at least to Brandon, Manitoba, and McHenry County, North Dakota, and southward in the Appalachians to Balsam, Jackson County, North Carolina.
Single brooded. Adults generally appear from late June to early August.
Have been reared on oak, hazel, birch, elm, beech, and Amelanchier, but seems to prefer willow.
