Wingspan: 25-35 mm (1) (2)
. Larvae to 30 mm (Massachusetts Division of Fisheries & Wildlife).
"Although there is variation in the extent of the brown shading, the general color, pointed apex on the forewing, and late-season flight period should be diagnostic" (2)
in the eastern United States.
"Spottily distributed from extreme southern Quebec and southern Ontario southward into northern Florida and Mississippi (2)
"Populations occur in habitats where the food plant is abundant or at least widely distributed. This includes dry sandy habitats like remnant oak savannahs, openings in oak woodlands, pine barrens, rock outcrops, and in open ridge-top woods. Some historical populations were on more disturbed sites such as an old gravel pit in New Haven County, Connecticut (in the late 1970s). Powerlines through barrens often provide habitat today. The sand plains of Wisconsin and probably Michigan, along with Appalachian shale barrens, are probably the strongholds for now Apodrepanulatrix liberaria
"On the wing from August through October, rarely as early as June" (1)
Listed as an endangered species in Massachusetts.
