Typical swarm locations
Collectors regularly attend swarms on the dune grassland and sea-buckthorn of St Mary's Island and the Brierdene to Seaton Sluice coastal margin, in the mature lime and horse chestnut of Park Avenue and the Rockcliffe estate, in the ivy-clad sea walls and garden borders of the promenade terraces, and in the chimney pots and eaves of the Edwardian boarding houses of the seafront.
