Green Hairstreak

Callophrys rubi

About

The Green Hairstreak is a small, fairly shy butterfly, which spends most of its time perched on vegetation or sunbathing. Adults fly in the spring, between April and June, and males can sometimes be seen chasing each other in the sun. Found in dry scrubby habitats, including moorland and heathland, the caterpillars feed on a variety of plants, including gorse, broom and bilberry.

How to identify

The Green Hairstreak is easily recognised by the combination of habitat, small size and the bright green undersides of the wings, with a faint streak of white spots. Upperside of wings is dull brown. Rests with wings closed.

How can people help

The Wildlife Trusts manage many grassland and woodland habitats sympathetically for the benefit of all kinds of butterflies, including the Green Hairstreak which has undergone declines in some areas. We are also working closely with farmers, landowners and developers to promote wildlife-friendly practices. We have a vision of a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.
