Typical swarm locations
Collectors regularly attend swarms in the garden trees and churchyard limes of the Market Hill and High Street conservation area, along the drain-bank scrub and willow carr of the Old Bedford River and Forty Foot Drain margins, on the field-margin hedgerows of the farms towards Somersham and Mepal, and in the eaves and chimney stacks of the older brick farmhouses and cottages in the fen lanes.
