Typical swarm locations
Collectors attend swarms in the mature garden trees of the Harestone Valley and Tupwood Lane residential areas, along the scrubby chalk scarp face and yew-wood margins above Gravelly Hill, in the old orchard and hedgerow trees of the Marden Park estate perimeter, in the Victorian and Edwardian terrace rooflines of the upper town near Caterham-on-the-Hill, and in the beech and oak boundary trees of the Pilgrims' Way lane.
