Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Cathedral precinct and Westgate conservation areas, along the Calder riverside willows and watermeadow margins at Thornes Park and Sandal, in the old parkland and walled garden remnants of Bretton Country Park and the Sculpture Park, and in the chimney stacks and eaves of the older Victorian city-centre properties.
