|scientific name Protogygia pallida |
Open sandy sagebrush grasslands.
In Alberta adults have been collected in late July and early August.
A medium-size (3.6-4.0 cm wingspan) immaculate creamy-white moth. The forewings including fringe are white. The hindwings are also white, with a variable fuscous wash, darker in females than males. Antennae in both sexes essentially filiform. Most likely to be confused with Copablepharon viridisparsum, which is larger, has a slight greenish cast to the forewings, and some evidence of a discal spot on the hindwings. The hindwings of viridisparsum usually have a grey patch in the center, variable in extent. Other white grasslands moths have at least some black markings (i.e. Cucillia luna) or bright orange on the forelegs and venter (i.e. Hyphantria cunea; Spilosoma congrua). This species was only recently described (2004); it was listed by Bowman as Copablepharon album.
Poorly known. Adults are nocturnal and are attracted to light.
