Description
The Gatekeeper or Hedge Brown as many people prefer to call it is most often found as these names suggest in gateways and hedgerows. It is often seen in association with Meadow Brown and Ringlet. Of these three butterflies, the Gatekeeper is probably the most attractive with its bright orange/brown wings fringed with a wide earthy/grey brown and distinctive black and white eyespot.

The colour and patterning of the wings can be very variable and there are several named aberrations. They are particularly fond of feeding on Bramble and Ragwort.


Habitat
The Gatekeeper occurs anywhere where tall grasses grow close to hedges trees or scrub, especially along hedgerows and woodland rides where there is a plentiful nectar source. It tends to avoid open grassland with short vegetation and areas where Bramble does not occur.

Larval Food Plants
Various grasses are used with a preference for fine grasses such as bents (Agrostis spp.) fescues (Festuca spp.), and meadow-grasses (Poa spp.). Common Couch (Elytrigia repens) is also used. The full range of other species used is not known.

British Subspecies
The following sub-species of the Gatekeeper occur in the UK.
