Habitat and Distribution

Eastern Tailed-Blue Hairstreaks are commonly found in meadows, woodland edges, open fields, and gardens across eastern North America. They prefer habitats with flowering plants for nectar and host plants such as legumes and clovers for larval feeding.

Behavior and Diet

Lifecycle

The lifecycle begins when females lay eggs on leaves or buds of host plants. Larvae feed on leaves while developing through several stages. Pupation occurs in leaf litter or on the host plant. Adults later emerge to feed, mate, and continue the reproductive cycle.
