Incisalia eryphon

Common Name:  Western Pine Elfin

Incisalia eryphon

Common at all the Sierran West slope sites. It has clearly moved upslope onto Castle Peak during the term of this study. Males perch around waist height on vegetation along roads and trails and in clearings, and are territorial.. Both sexes visit Ceanothus and other spring flowers, but seldom at ground level. One brood in mid-spring, May-June at Washington, June-July at Donner and Castle Peak. The hosts are "hard" pines (Ponderosa, Jeffrey and Lodgepole, in our area; most common where Lodgepole is dominant).
