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.
The species ranges from southern British Columbia and Alberta south through most of the Pacific Northwest and eastern California, and east to western Montana south to northern New Mexico. Isolated populations may be found in North Dakota, Nebraska and southeastern New Mexico. It occurs in patches throughout the state of Idaho.
It occurs in chaparral, woodlands, sagebrush steppe, and scrublands.
Caterpillars eat the leaves of a variety of wild buckwheat (Eriogonum)
Adult: Butterflies drink flower nectar.
Usually 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 March to July.
Males perch to wait for receptive females to pass by. Females lay eggs singly on the leaves of host plants.
