A rare spider, thought to be extinct in the UK, has been photographed for the first time in a new colony in the Fens.

The Rosser's sac spider, which had not been seen for 10 years, has been discovered at Chippenham Fen in Cambridgeshire.

It likes to live in wetland areas .. and had been found only once before at Lakenheath Fen in Suffolk.

The light brown spider was first found in the 1950s but the draining of the Fens and changing farming practices had put it under threat.
