Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Market Square and High Street conservation areas, in the ancient beechwood and scrub margins of the Chilterns above Little Missenden and Coleshill, along the Chess riverside willows and watermeadow margins at Chenies and Sarratt, and in the chimney stacks and eaves of the older medieval and Georgian town-centre properties.
