After a period of dramatic decline, the Large Blue butterfly became extinct in Britain in 1979.
Its re-introduction in 1992 to the Polden Hills in Somerset has been one of the world’s most successful conservation programmes.
Scientists discovered the butterfly is reliant on a particular red ant - myrmica sabuleti. Large Blue caterpillars feed on Wild Thyme flowers before ants carry them underground into their nest. The caterpillars then feed on ant-grubs before pupating and emerging above ground as butterflies.
Changes in grazing and clearance of overgrown grassland has created Large Blue and red ant friendly habitat but it is not enough to secure the future of this species. The butterfly must colonise more of the countryside if it is to survive accidental habitat loss or damage, variations in weather and the adverse impact of climate change.
The Large Blue remains one of the world's most threatened species and is classified as endangered in Europe, due to its continued rapid decline.
