Identification

Season
adults fly from May to October in California
Food
larvae have been collected from damaged and decaying seedpods of two lupine species: Silver Lupine (Lupinus albifrons) and Broadleaf Lupine (L. latifolius); larvae are presumed to feed on detritus within the decomposed seedpods (see Wagner document in References sections below)
Life Cycle
overwinters as a larva in seedpod of hostplant
