Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Market Square and High Street conservation areas, along the Grand Union Canal towpath willows and hedgerow margins at Slapton and Horton Wharf, on the chalk grassland and scrub margins of Ivinghoe Beacon, and in the chimney stacks and eaves of the older Victorian and Edwardian town-centre properties.
