Insect feared to be extinct in Britain for almost 30 years ‘comes back from dead’

A species of insect feared to have gone extinct in Britain is set to 'come back from the dead' after 28 years following pioneering conservation work at a UK zoo.

The tiny river fly, known as scarce yellow sally, was thought to have died out back in 1995.

However, when a small number were rediscovered in a short stretch of the River Dee in North Wales, scientists launched a rescue mission to try to save them.

Now, the critically-endangered creature has been bred by a team of aquarists at Chester Zoo.

Experts plan to release it back into the wild.
