The devil's coach-horse beetle (Ocypus olens) is a species of beetle belonging to the large family of the rove beetles (Staphylinidae). It was originally included in the genus Staphylinus in 1764, and some authors and biologists still use this classification.
The Latin species name olens, meaning "smelling", refers to the two white stinking glands on the abdomen. This beetle has been associated with the Devil since the Middle Ages, hence its common name, which has been used at least since 1840. Other names include devil's footman, devil's coachman, and devil's steed. It is sometimes also known as the cock-tail beetle for its habit of raising its abdomen.
One dictionary suggested that the name developed in parallelism with ladybird and its Norse cognates. In Irish, the beetle is called dearga-daol or darbh-daol. The Irish also called it "the coffin cutter." British folklore has it that a beetle has eaten the core of Eve's apple, and that a person who crushes such a beetle is forgiven seven sins. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Devil's Coach Horse Beetle is recorded against all the insects logged in Cévennes National Park (21 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.
