Typical swarm locations
Collectors regularly attend swarms in the older walled garden remnants and lime trees of the Castle Hill and Market Square conservation areas, along the Lune riverside willows and watermeadow margins at Halton and Skerton, on the limestone grassland and heather margins of the Bowland Fells above Quernmore, and in the chimney stacks and eaves of the older Georgian and Victorian city-centre properties.
