Frigga Fritillary
Boloria frigga
The Frigga Fritillary is a northern species that is limited in distribution and habitat in Wisconsin. The Freija Fritillary may fly in the same area as the Friggaa Fritillary, but rarely at the same time. It is most likely to be seen flying with the Silver-bordered Fritillary or the Bog Fritillary and could be confused with these species only in flight.
