The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Megachile dorsalis - Silvery Leaf-cutter Bee



Range & Status

Principally restricted to coastal sites in southern England and Wales where it is associated with the wind-blown sands of coastal dunes. Here it normally frequents the mid-dunes and requires warm, sunny, areas such as south facing slopes for nesting. Previously known as M. leachella or M. argentata , this species is present on a large proportion of our major Cornish dune systems where some of the populations are extremely large. There are at least 20 post-1980 sites and in many of these the bee can be observed cutting and using the foliage of Traveller' s Joy Clematis vitalba to line the cells of its nest.
