Typical swarm locations
Collectors in Cottenham regularly attend swarms in the waterside willows and willowherb margins of Cottenham Lode and the surrounding fen-edge drainage dykes, in the older garden fruit trees and privet hedges of the High Street and Rooks Street conservation area, in the elder and hawthorn field margins of the surrounding clay arable fringe towards Rampton and Willingham, and in chimney stacks and eaves of the older red-brick village properties.
