Previously Osmia rufa (Panzer,1806). This species has gained a notorious reputation from the females' habit of excavating their nesting burrows and cells in crumbling or soft mortar joints, thereby, in time, undermining and possibly weakening the fabric of masonry. The bee also utilises existing holes. It is colloquially known as the red mortar bee or red mason bee.
Widely distributed throughout much of Britain as far north as Perthshire. A common species, except in parts of northern England and in Scotland. A recent arrival in Ireland. There are a few old records from the Channel Islands. The species is found throughout much of the Palaearctic, the range extending from Sweden and Denmark, south to Spain and Morocco, and east to Japan.
