Typical swarm locations
Collectors attend swarms in the older Victorian and Edwardian terrace properties along the seafront and town centre, along the Dyfi estuary saltmarsh and sea-aster margin below the town, in the dune and marram grassland behind the beach toward Tonfanau, on the gorse-covered hillside above the town on the Tywyn road common, and in the farm outbuildings of the Dyfi valley floor farmland between Aberdyfi and Pennal.
