British Large Blue
(Maculinea arion eutyphron)

 
syn. -

 
distribution:

Great Britain

 
local name:

Large Blue - Great Britain

 
size: (?)

extinction date: around 1970

 
As all species of its genus, the Large Blue is an extremely specialised species, which has very special demands on its habitat.

Area-wide destruction of habitats trough intensive agriculture, but also the collecting of the butterflies themselves, led to the extinction of the former endemic british subspecies.

During the 1980-s the nominate race from Sweden was introduced to the south of Great Britain, so at least the Large Blue as a species does still occur in Great Britain.

The dutch form of another species of this genus, the Alcon Blue (Maculinea alcon arenaria), formerly treated as a seperate extinct subspecies, is now, after DNA analyses, considered as conspecific with the nominate race.
