Note: The green hairstreaks of the genus Callophrys can be difficult to identify. There is still some debate among scientists about the exact boundaries between some species.
This is a western species, ranging from southern British Columbia and Alberta south through the Pacific Northwest and California, and east to central Montana and south to New Mexico. It has been found scattered throughout the state of Idaho.
Generally this species is found on open sunny slopes with low vegetation. This includes sand dunes, chaparral, brush, and forest openings.
Caterpillar: Caterpillars eat the flowers, fruits, and occasionally leaves of several species of plants, including buckwheat (Eriogonum spp.), trefoils (Lotus spp.), and buck brush (Ceanothus spp.).
Adult: Butterflies drink flower nectar.
There is one generation of caterpillars each summer. The caterpillars pupate, then overwinter within their chrysalises in a physiological state called diapause until spring. Adults generally fly from May through June.
Males perch and wait for receptive females to pass by. Females lay eggs singly on the flower buds of host plants.
