Solenopsis fugax

Solenopsis fugax is a myrmicine ant of the genus Solenopsis.

It is the only member of its genus to be native to the British Isles, and although rare, it has been taken by Horace Donisthorpe in a number of localities on England's southern coast, including Sandown and Shanklin on the Isle of Wight, and also in the southwesterly region of Lyme Regis. It can be found throughout Europe and Central Asia and some parts of South West Asia.

The species is a thief ant and usually has its nest near another species, stealing food by entering the foreign colony through minute tunnels dug from their own nest.
