Typical swarm locations
Collectors regularly attend swarms in the old flint and chalk-block properties of the High Street and St Mary's Street conservation area, along the Thames towpath between Wallingford Bridge and Benson, in the churchyard and parkland trees of the town mound and castle earthworks, on the chalk grassland margins of Wittenham Clumps above Little Wittenham, and in the chimney pots of the older Georgian and Victorian brick properties.
