Mountain butterflies 'will have to be relocated as habitats get too hot'

Populations of mountain ringlet in Lake District face being wiped out as cooler habitats disappear

The diversity and resilience of cold-loving butterfly species is threatened by global heating which will destroy genetically unique populations, according to a study.

Native mountain-dwelling butterflies such as the mountain ringlet, the bright-eyed ringlet and the dewy ringlet will have to be translocated to higher altitudes as their cooler habitat disappears to avoid extinction.
