Aside from being frequent in the Channel Islands (whence its common name comes), this species was rarely seen in the British Isles in Victorian times. It was described by William Forsell Kirby as, "a great rarity in the South of England, except one locality in Devonshire." Since then however it has spread more widely in Devon and Cornwall, and has recently been seen more frequently in southern England, especially on the Isle of Wight, in northern Kent,Ferguson, I. D.

They have been seen regularly and in numbers every year in London first discovered at Devonshire Road Nature Reserve in Forest Hill since 2004, so it is probable that they have established a breeding colony.Jersey tigers on UK Safari page
