Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Valley Gardens and Cheltenham Conservation Area, on the limestone grassland and scrub margins of the Nidderdale AONB above Ripley, along the Nidd riverside willows and watermeadow margins at Knaresborough and Bilton, and in the chimney stacks and eaves of the older Victorian spa and Georgian hotel properties.
