Native. Mediterranean-Atlantic. Found as a native species mostly in coastal areas in
southern Britain south of a line from the River Severn to The Wash, the Channel Islands and very rare in south-eastern Ireland.
Rare in the Isles of Scilly where it is found on three inhabited islands. There are three
post-1990 records from Cornwall: Trevone (SW87), Cury (SW62), and near Millandreath (SX25) ), with most older records from south-east Cornwall.
