AdultBehr's Hairstreak is easily identified by the tawny orange of the upperside of the wings and the wide black area on the costal area of the dorsal forewing. The pattern of the ventral hindwing is also characteristic of the species.
Immature StagesComstock (1928) described the immatures. The mature larva is green, matching the foodplant leaves. It has a narrow dorsal white line edged by a wider dark green area on each side.
SubspeciesThe BC subspecies, S.b. columbia (McDunnough, 1944), was described from specimens collected at Fairview [Oliver], BC. It ranges south in Washington along the east side of the Cascade Mountains.
