Erica tetralix
This polyphagous species probably has one of the largest range of food plants of any British butterfly. Early butterfly collectors thought that the only food plant was bramble (blackberry) "Rubus fruticosus" but as its habits became better understood the list grew and will probably continue to do so. Depending on the habitat it will use common rock rose "Helianthemum nummularium", bird's-foot trefoil "Lotus corniculatus", gorse "Ulex europaeus", broom "Cytisus scoparius", Dyer's greenweed "Genista tinctoria", bilberry "Vaccinium myrtillus", dogwood "Cornus sanguinea", buckthorn "Rhamnus cathartica", cross-leaved heath "Erica tetralix" and bramble.
