Cliff Mason Bee
Osmia xanthomelana
Osmia xanthomelana, the large mason bee, is a species of mason bee in the genus Osmia. It has a wide distribution in the Palearctic but it is rare wherever it occurs and, for example, in Great Britain it has a highly restricted distribution, although in the past it was a little more widespread there.

Description
Osmia xanthomelana is a medium-sized bee, measuring 12–13mm in length with a stocky, robust structure. The main colour is black but it has golden to brown hairs which cover the face and thorax becoming sparser and paler on the abdomen.
Range & habitat
Osmia xanthomelana is widely distributed throughout the Palearctic but it is apparently rare wherever it occurs. In Great Britain it is currently found only in two locations on the Llŷn Peninsula, in Gwynedd, Wales.
