AN endangered species of moth has been found on Dartmoor. Although once a common sight throughout the UK, populations of narrow bordered bee hawk moths (pictured) are now concentrated in the South West. The moth, which lives alongside the equally rare marsh fritillary butterfly, was found in eight areas covered by Defra?s Environmentally Sensitive Area Scheme ? an initiative that rewards farmers and landowners who take measures to protect rare species. Biodiversity minister Jim Knight said the sightings showed ?how the scheme (which encourages grazing rather than arable use of limestone grassland) has created a habitat that allows scarce species to thrive? . ?Moths are vital to the countryside ? moth caterpillars are an important part of the food chain for many of our native and migratory birds, and animals from beetles and earwigs to lizards and small mammals rely on moths for food,? he said. A number of environmental organisations have been established in recognition of the area?s importance for butterfly and moth conservation. The Two Moors Threatened Butterfly Project, which covers both Dartmoor and Exmoor, was launched earlier this year and is working with landowners and farmers to give advice on butterfly friendly farming practices. A similar project on the Culm grasslands between Exmoor, Dartmoor and North Cornwall is also looking at ways of protecting habitats for the narrow bordered bee hawk and the double line moths. As many as 50 native moth species face extinction and it is hoped that renewed interest generated by these organisations and events such as last week?s National Moth Night and Day will raise the profile of conservation efforts.
