The Marsh fritillary

The Marsh fritillary (Euphydryas aurinia subsp. provincialis) is a butterfly named in French after its orange chequered pattern on its wings. As for the Devil's-bit scabious, it is one of the host plants for the caterpillar form of the Marsh fritillary. Although it is present in most of the country, the Marsh fritillary is usually rare and localized. In Provence, the subspecies "provincialis" is relatively common in places like Mourres and can be seen around April-May. This butterfly is protected in France.
