Species virginarius (Panthea virginarius - Hodges#9178 )
Hodges Number
9178
Synonyms and other taxonomic changes
Originally described as Biston virginarius by Grote in 1880
synonym Panthea portlandia Grote, 1896 (Hodges 9179)
synonym Panthea angelica Dyar, 1921(Hodges 9180)
synonym Panthea suffusa McDunnough, 1942
specific epithet also spelled "virginaria" (Biston is masculine, Panthea is feminine- so "virginaria" is technically the correct form, while "virginarius" preserves the original spelling).
Identification
Adult - varies greatly in size and color pattern depending on location and habitat. Both sexes of P. virginarius can be very difficult to separate from those of P. gigantea where they occur together unless genitalic characters are used
Range
mainly west and north of the Great Basin, from the coast of southern California northward to the Queen Charlotte Islands of British Columbia and the Alaskan Panhandle, eastward to central California,northern Nevada, Idaho, northwestern Wyoming, western Montana, and southwestern Alberta; a disjunct population is in the Cypress Hills of Alberta and Saskatchewan. Large black and white populations (syn. portlandia) occur along the coast from central California to southern British Columbia. These are replaced by gray and black populations both farther north and farther south along the coast, and at higher elevations inland. Intermediate populations occur at lower elevations eastward as far as western Montana and extreme southwestern Alberta
Habitat
coniferous forests, in particular but not confined to Douglas-fir Pseudotsuga menziesii forest at elevations ranging from sea-level to near tree-line
Food
larvae feed on leaves of Douglas-fir (Pseudotsuga menziesii)
See Also
light forms of P. virginarius are very similar to the Black Zigzag (P. acronyctoides) but have a less prominent orbicular spot, and less dark gray shading along inner margin and at base of forewing (compare images of both species by Jim Vargo at MPG)
darker forms are more uniformly gray, and less likely to be confused with the Black Zigzag (compare images of both species at CBIF)
