Typical swarm locations
Collectors regularly attend swarms in the canal-side willows and alder carr of the Kennet and Avon towpath at Thatcham and Aldermaston Wharf, in the watermeadow and reed-bed margins of the Nature Discovery Centre, along the older residential hedgerows and garden trees of the town fringe, and in the chimney stacks and eaves of the older town-centre and Kennet-valley village properties.
