Andrena simillima - A solitary mining bee

Range & Status

Once widespread in southern England but now in rapid decline. Although found on

heathland and chalk downland elsewhere, in Cornwall most of it extant sites are in coastal situations, including soft rock cliffs, land slips and dune systems. Here it nests in patches of bare or sparsely vegetated ground in warm situations on south facing slopes and banks. There are numerous older records and at least 10 post-1980 sites, and it is to be found on both north and south coasts. Cornwall is considered to be one of the strongholds for this species.
