Marsh Fritillary (Euphydryas aurinia)
Now very rare in the county and very susceptible to local extinction because of the activities of parasitic wasps Marsh Fritillaries may possibly still be found where the larval foodplant Devil’s Bit Scabious occurs, both on dry limestone grassland sites and in wet grassland or moorland. The sexes are similar though females are sometimes slightly bigger and paler.
Images L-R: female; underside; female above, male below (note different abdomen shapes).
Flight period: mid May to early July
Because of their rarity no distribution map is given.
