Silver-bordered Fritillary

Boloria selene

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.

Weekly sightings for Silver-bordered 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 does not have the silver border above.

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.
