The large chequered skipper (Heteropterus morpheus) is a species of butterfly in the family Hesperiidae. It is the single member of the monotypic genus Heteropterus. The species can be found in isolated populations in Europe and east across the Palearctic to Central Asia and Korea. It is endangered in the Netherlands.
The length of the forewings is 15–18 mm. The butterfly has a very distinctive and attractive underside but a drab upperside (which is rarely seen, as it usually settles with wings closed). The upper side is quite dark brown and it is the reverse which is characteristic with brown fore wings in part covered by the hind wing and in the visible part the same ornamentation as the hind wings, on an ochre ground three lines of spots white ovals surrounded by black and a white border cut with black.

GBIF citizen-science records
It is estimated from how often the Large Chequered Skipper is recorded against all the insects logged in Biebrza National Park (7 verified sightings from 2019 to 2026), 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.
