The high brown fritillary (Fabriciana adippe) is a large and brightly colored butterfly of the family Nymphalidae, native to Europe and across the Palearctic to Japan. It is known for being Great Britain's most threatened butterfly and is listed as a vulnerable species under the Wildlife and Countryside Act 1981. Like other fritillaries it is dependent on warm climates with violet-rich flora.
The high brown fritillary's wingspan is on average around 65 mm. Its upper wings are orange with black markings and the undersides are colored a duller orange with white and brown markings. While flying, it is very hard to distinguish from the dark green fritillary which has many of the same markings. The male and female fritillary share many of the same physical features.
Larvae are brown with a single longitudinal white stripe down the length of their body. Their bodies are covered in brown spikes which aid in camouflaging them from predators as they move among dead fern fronds. A. adippe L. (= berecynthia Poda, cydippe L.) (69d). Usually larger than the previous species [ Argynnis alexandra Ménetries, 1832], the wings

GBIF citizen-science records
It is estimated from how often the High Brown Fritillary is recorded against all the insects logged in Triglav National Park (22 verified sightings from 2019 to 2026), calibrated against known sighting rates.
