Typical swarm locations
Collectors regularly attend swarms in the old flint-and-brick garden walls and mature trees of the High Street and Brook Street conservation area, on the chalk grassland and beechwood scrub edge of Watlington Hill, in the orchard and hedged lane remnants of the Pyrton and Shirburn estate villages, along the Little Thames valley willows south of the town, and in the chimney stacks and roof voids of the older market-town properties.
