Typical swarm locations
Collectors attend swarms in the beechwood margins and chalk grassland of the Chiltern scarp above Coombe Hill and Bacombe Hill, along the derelict Wendover Arm towpath willows and watermeadow margins, in the old orchard remnants and lime trees of the High Street and Aylesbury Road conservation area, and in the chimney stacks and eaves of the older brick-and-flint Chiltern cottages and Georgian market-town terraces.
