Boloria dia, the Weaver's fritillary or violet fritillary, is a butterfly in the family Nymphalidae. The name Weaver's fritillary is in honor of Richard Weaver (fl. 1790-1860), an English insect collector who claimed to have obtained the specimen within ten miles of Birmingham around 1820.[1] However, B. dia is uncommon in England and the few specimens known from there are thought to be from possibly accidental introductions.[2]
Description[]
The adult is a small fritillary with typically chequered orange-brown upperside and a submarginal row of triangles and dots. The forewing is 16–17 mm long. The underside of the hindwing has a distinctive purplish band.
B. dia differs from the pearl-bordered fritillary in having a sharp angle to its hindwing (readily seen from underside when perched with wings closed). The similar Titania's fritillary has a less sharply-angled hindwing and only occurs at high altitude.[3]
In Europe the larvae feed on Viola species (Viola odorata, Viola hirta, Viola canina, Viola reichenbachiana, Viola tricolor), and outside Europe on Prunella vulgaris and Rubus idaeus.
Distribution[]
B. dia is found in Europe, over the Caucasus east across the Palearctic to Mongolia. It is widespread and common across southern France.[3] In Europe it occurs from northern Spain, Italy and Greece to Poland, the Balkans and Turkey.[4][5] It is not found in Britain.
