With its chalk-white face and bright flame-coloured markings, the white-faced darter dragonfly is a distinctive sight as it flutters around England’s peat bogs.

The rare dragonfly, which breeds in mossy pools, is at threat of local extinction, but now conservationists are trying to end its population crash by introducing it into a remote corner of Cumbria.

White-faced darters are being carefully transported to the South Solway Mosses national nature reserve, where mossy pools have been created for the insects to enjoy. They thrive in bogs, breeding in acidic pools containing sphagnum moss, and roost and feed in woodlands.
