Typical swarm locations
Collectors regularly attend swarms along the Old West River and Haddenham bank waterside willows and alder carr, in the hawthorn and elder of the old fen embankment hedges at Aldreth and Wilburton, in the mature lime and sycamore of the village centre churchyard and manor grounds, in the oilseed rape margins and field-edge scrub of the fen fields west of the village, and in the chimney stacks and eaves of the older brick and clay-lump cottages throughout Haddenham and Aldreth.
