Open areas such as fields, meadows, roadsides, and clover fields across North America.

Diet & Feeding

Adults feed on flower nectar (often from clover and alfalfa); larvae (caterpillars) feed on various legumes.

Behavior Patterns

Active during the day (diurnal), they are known for 'puddling' where large groups gather on damp mud to drink minerals. They have multiple generations per year and overwinter as larvae.

Risks & Benefits

Benefits the ecosystem as an important pollinator; larvae can sometimes be minor agricultural pests in legume crops but are generally not a serious threat.
