Did You Know…
The yellow-green eyes separate this species from all other similar species except for the Great Spangled Fritillary (Speyeria cybele). Males patrol for females during warm hours. Females walk about on the ground to lay single eggs near violets. First-stage caterpillars do not feed, but overwinter until spring, when they eat young leaves of violets.
