Megachile centuncularis, commonly known as the patchwork leafcutter bee, is a species of bee in the family Megachilidae. It was first described by the Swedish naturalist Carl Linnaeus in 1758. The Megachilidae are long-tongued, solitary bees, characterized by a rectangular labrum, the flap-like structure at the front of the mouth. They carry pollen on hairs on the underside of the abdomen. This species is about two centimetres (0.79 in) long and is largely black, the abdominal segments being fringed with golden hairs and the underside of the abdomen being clad with orange hairs.
Megachile centuncularis is native to the northern hemisphere, being present in both North America and Eurasia. In western Europe, its range extends from Norway, Sweden and Finland southward to Spain and Italy. It occurs in eastern Ireland, and in Britain, especially in the southern part of the country. It is generally a common species and visits gardens in both rural and urban areas.
The adult bee feeds on nectar obtained from various flowers, particularly thistles and brambles. It collects pollen to provision the nest from a wide range of flowers, including... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Patchwork Leafcutter Bee is recorded against all the insects logged in Paris (15 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.
