Stenopterus ater is a species of longhorn beetle found across the Western Mediterranean region from North Africa to France and Italy. The larvae grow in dead wood and the adults visit Umbelliferae flowers in summer. They are about 6 to 14 mm long with males and females being differently coloured. The elytra are all black in females and yellowish brown in males. A case of gynandromorphism has been recorded in the species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Stenopterus ater is recorded against all the insects logged in Algiers (12 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.
