Caterpillars feed on a variety of grasses such as fescues and meadow-grasses.

How people can help

The Wildlife Trusts work closely with farmers and landowners to ensure that our wildlife is protected and to promote wildlife-friendly practices. By working together, we can create Living Landscapes: networks of habitats stretching across town and country that allow wildlife to move about freely and people to enjoy the benefits of nature.
