Life Cycle & Host Plants

Females lay individual eggs on host plants. Fully grown caterpillars from the later brood overwinter. [1]

Host Plants & Changing Range

Use of introduced crown vetch has helped this species spread along transportation corridors. Native wild indigos remain important hosts; the presence of a host plant is a clue, not proof of identification. [1]
