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.

Andrena thoracica

Range & Status

Locally common in coastline localities in southern England and southern and west Wales. It is also known from inland sites often on heathy soils. This species is found in open, sandy-grassland, particularly where these are associated with exposed vertical cliffs, which provide favoured nesting sites. This species has undergone a rapid decline in recent years, however, in Cornwall it is still relatively common, especially in coastal sites, where there have been at least 20 post-2003 records. There are also small populations of this bee on various islands in the Isles of Scilly archipelago.
