"The white-faced darter dragonfly was last recorded in the country in 2003.
Cheshire Wildlife Trust (CWT) have placed 100 larvae into pools in Delamere Forest in the hope that they will thrive.
It is only the second time a dragonfly reintroduction has been attempted, following a project in Cumbria in 2010.
The dragonfly, which CWT said was 'one of the UK's rarest', is only found in Cumbria, Staffordshire, Shropshire and Scotland.
The Cheshire project saw larvae collected from healthy populations in pools in Shropshire and Staffordshire and relocated to the forest." - BBC News, May 29, 2014
