About Icaricia lupini
Icaricia lupini, commonly known as the lupine blue, is a butterfly species belonging to the family Lycaenidae. This butterfly is distributed from southwestern Canada, extending south through most of the mountainous and intermountain regions of the western United States and the high plains, reaching as far south as northern Mexico. The wingspan of adult Icaricia lupini ranges from 22 to 29 mm. In the Sierra Nevada of eastern California, adults are active from June to August, producing one generation per year. In other parts of its range, this species produces multiple generations from March to July. The larvae feed on Eriogonum umbellatum and Eriogonum fasciculatum. Adult butterflies feed on flower nectar. The hairs of Icaricia lupini caterpillars can cause skin irritation known as urticaria.
