The Isles of Scilly has enhanced its reputation as an area of biodiversity after two nature devotees found a rare cricket on the islands.

Ren Hathway and Paul Stanclife found the large cone-headed cricket on St Marys.

This is thought to be the first recording of the insect in Britain, as they usually inhabit much warmer climates.

The male has a loud mating call which can be heard up to two miles away although no females have been found as of yet.

A formal identification will be undertaken when a sample is sent to the Natural History Museum in London.
