Rarest of all the Haploa species. Only one record from Allegany County, although John Glaser considered the species "uncommon" in western Maryland (Glaser, Line 2005).
One of four Haploa species with white hindwings. A dark line runs from the middle of the margin of the forewing diagonally downward towards the tornal bend of the forewing. This dark line is usually met by another dark line that starts just below the forewing apex. There are two thin dark lines that meet this line from the hindwing margin. All white individuals are indistinguishable from other all white Haploa species.
Larvae feed on a variety of woody and herbaceous plant species.
