Similar Species
In Central Europe, a confusion with different Perlmutterfaltern the genera Boloria, but also for beginners Brenthis and perhaps Argynnis is possible. Last, however, are much larger.

- Alpine meadows Fritillary ( Boloria pales ) - inter alia Alps
- Similar Fritillary ( Boloria napaea ) - inter alia Alps
- Snake root Fritillary ( Boloria titania ) - among others Alps

- Meadowsweet Fritillary ( Brenthis ino ) - medium altitudes

Flight time
The moth flies in one generation from mid-June to August.
Habitat
The raised bog fritillary, is dependent on the presence of raised bogs and acidic, nutrient-poor intermediate marshes, where the food plant of the caterpillar grows. However, the adult moth appears in search of nectar plants often also on adjacent fens, meadows and along roadsides.
Way of life
The caterpillars feed on the ordinary cranberry ( Vaccinium oxycoccos ) and hibernate.
Dissemination
The raised bog fritillary has newer evidence from almost all the German states, but often only occasional, small bog residues ( eg, Rhineland -Palatinate and Hesse). The butterfly is found in South Belgium ( Ardennes with small, widely scattered populations), France ( Massif Central, Orne, Eure, Seine- Maritime, Nièvre, Jura, Doubs, Haute -Saône, Haut-Rhin, Vosges ). From Switzerland, he is known in the Jura, Alps and the Engadine. Furthermore, it is found in Austria, the Czech Republic, Slovakia, Poland to the Baltic. In Fennoscandia including Zealand it is widespread and common. Since many were drained raised bogs in the past and destroyed except for a few miserable remnants of the peat degradation, the species has become extinct or very rare in many areas.
