Distribution
Eastern North America, from southern Ontario and New England west to Minnesota and south to Texas and Florida. Present throughout the eastern United States with scattered records in adjacent Canadian provinces.
Seasonality
are active from late May through August, with peak activity in June and July. One to two per year depending on latitude.
Diet
Larvae feed on leaves of leguminous plants, particularly in the Lespedeza and Desmodium. feed on nectar from various flowers including milkweeds, dogbanes, and other summer-blooming plants.
Host Associations
- Lespedeza - larval foodplant
- Desmodium - larval foodplant
Life Cycle
are laid singly on plant leaves. Larvae construct leaf shelters by folding or tying leaves together with silk. occurs within these shelters or in leaf litter on the ground. Overwinters as a partially grown larva.
Behavior
perch on vegetation with wings partially open, darting out to investigate intruders or potential mates. Males are territorial and establish perches in sunny openings. Both sexes visit flowers for nectar and are rapid, erratic fliers typical of skippers.
