Typical swarm locations
Collectors regularly attend swarms on the heather and gorse of the Wharncliffe Crags and Chase above the valley, in the alder and willow carr of the Little Don at Deepcar and Oughtibridge, in the lime and sycamore of the older Stocksbridge terraces, and in the stone-built industrial building eaves and redundant steelworks masonry along the valley floor.
