Breeds in southern England, the Channel Islands and southernmost Wales, in western France and on the Mediterranean coast and throughout Iberia. Also breeds on Menorca, on Corsica and Sardinia, southern Italy and north-east Sicily and in coastal North Africa in Morocco, Algeria, and Tunisia.

Britain lies on the northern edge of this species' range and it occurs mainly in southern England with the bulk of the population found from Devon to Sussex and Surrey with small numbers in Cornwall and on the Isle of Wight. With global warming, the species has increased and spread north in recent decades, and now breeds in coastal heaths in south Wales, Essex, Suffolk and Norfolk; extralimital breeding has also occurred in north Wales and Staffordshire.[2]

Vagrants have been recorded in Ireland, Scotland, Belgium and the Netherlands, Germany and Sweden, and east to Greece and the former Yugoslavia, and also in Libya.

Taxonomy

This is a polytypic species[1] consisting of 3 subspecies.
