The Silver-bordered Fritillary gets its name from its very distinctive light colored border. This species and the Meadow Fritillary are both found throughout the state and are often flying about the same time. This species is more of a wetland butterfly, and is found in moister areas than the Meadow Fritillary.
Identifying characteristics: Above this species is orange with black spots and a light, silver-colored border on both the upper and the hindwing. Below, on the hindwing, this species has a reddish-orange color with a row of white dots near the margin and other conspicuous white markings throughout.
Similar species: The Purplish Fritillary also has a light border, but is generally darker above and has a row of thin white spots on the hindwing margin and a purplish sheen below. The Bog Fritillary looks very similar below, but above does not have the silver border.
Habitat: Wet meadows throughout Wisconsin.
Flight: Two broods. This species may be found from early May through August.
Abundance: Like the Meadow Fritillary, this species is often found flying singly, but can become somewhat numerous. I have seen over 50 of this species in a single day.
