Status (B.C.): Red listed
Propertius Dusky Wing Butterflies are brown to purplish, to dark grey, with an array of white spots across both sets of wings. Early and late phase instars (larvae) are sage green, with yellow sub-dorsal lines and rings, as well as a distinct orange spot on their heads. In Canada, the only known host plant for E. propertius’ larvae is Garry oak. This species can be found from sea level to mid-elevation areas with open Garry Oak stands or mixed woodlands where Garry Oak occur.
