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

Rare
Under 5% of wildlife watchers report a High Brown Fritillary sighting in Prague on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 647th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the High Brown Fritillary is recorded against all the insects logged in Prague (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
