Typical swarm locations
Collectors regularly attend swarms on the heather and bilberry moorland fringe of Langsett and Dunford Bridge, in the hedgerow hawthorn and old farm orchards of the Thurlstone and Ingbirchworth plateau, in the mature lime and sycamore of the Penistone town centre and market, and in the stone-built farm eaves and barn roof voids of the surrounding hill farms above the Don.
