The large tortoiseshell or blackleg tortoiseshell (Nymphalis polychloros) is a butterfly of the family Nymphalidae. The species is found in North Africa, southern and central Europe, Turkey, southern Russia, the central and southern Urals, Kazakhstan and the Himalayas. In Central Europe it occurs mainly in warmer regions and has become generally rare, while populations remain more numerous in parts of the Mediterranean region and the southern Alps.
Large tortoiseshells inhabit open woodland, woodland edges and clearings, as well as orchards, hedgerows and areas of scattered trees. The larvae feed on a variety of deciduous trees including elm, poplar, willow and related species, while adults are often found basking on tree trunks or feeding on sap runs, overripe fruit and honeydew.
The species also occurs in Great Britain, where it has recently begun to re-establish itself following a prolonged absence. The large tortoiseshell was formerly widespread throughout England and Wales... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Large Tortoiseshell is recorded against all the insects logged in Berlin (21 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.
