Hodges Number
Widely distributed over Alaska, occurring as far north as Umiat (69°25'N lat.), westward to the Pribilof and St. Lawrence Islands, and as far south as Oregon. It is the most boreal of all the Nearctic Incurvarioidea, being one of only two species in this superfamily known to occur north of the Arctic Circle. (1)
Currently unknown(2)...but has been found among ericaceous shrubs, and a few herbaceous plants, see Matt Goff's comment here.
As its specific name suggests, this species demonstrates the greatest variation in maculation of all New World Prodoxidae.
