Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the St George's Square and New Street conservation areas, on the heather and bilberry moorland margins of Castle Hill and the Holme Moss plateau, along the Holme and Colne riverside willows and watermeadow margins at Ravensknowle Park, and in the chimney stacks and eaves of the older Victorian textile-town properties.
