Field notes and information
One of the first fritillaries to fly in spring.
Identification & Similar species: Similar to the small pearl bordered fritillary, C. selene, which has a row of post discal spots on the upperside hindwing displaced to the margin. In the current species this row is equidistant between the submarginal markings and the discal markings. The underside has a row of bold black spots in the post discal area vs pale spots in the current species. The current species has just one bright patch in the discal band of the underside hindwing.
Distribution & Flight: From north Spain across most of Europe. Flies in a single brood in spring from April to June or July depeding on altitude. A partial second brood is reported from hot southerly locations.
Habitat & Behaviour: Flowery clearings in woodland. Sometimes alpine flowery grassland where it may be found a long way from forest.
