Typical swarm locations
Collectors attend swarms in the older stone and rendered properties of the town centre and the school lane, along the Glaslyn and Dwyryd estuary saltmarsh and hawthorn scrub margins, in the Portmeirion estate woodland and parkland to the south of the town, on the hillside above the town toward Croesor and the Moelwyns, and in the farm outbuildings of the valley-floor farmland between Penrhyndeudraeth and Garreg.
