Identification
Wings white, with heavy black spotting on forewing and variable black subterminal patches on hindwing. Abdomen with yellow areas & black spots.(1)
Range
Canada & eastern US, but rare south of New York(1)
According to Dale Schweitzer, the species "actually does not occur at all in the vast majority of the US range shown" in the Peterson Guide. "Basically, it occurs across Canada and adjacent counties in US, then again from southeastern NC to FL, and not in between". The southern Coastal Plain part of the range apparently extends as far west as eastern Texas. Schweitzer suggests that the southern coastal plain entity may in fact be a different species than the northern Canadian zone entity. The Moth Photographers Group map for the species shows numerous "dots" in the area between these two populations, which are certainly based on misidentifications of similar species.
