Typical swarm locations
Collectors attend swarms in the older terraced properties of the village centre and Stryd Fawr, in the Llyn Padarn Country Park mature woodland and parkland margins, along the lower slopes of the Pass of Llanberis hawthorn and elder scrub toward Pen y Pass, in the Dinorwic quarry-side birch and heather scrub above the National Slate Museum, and in the farm outbuildings and walled-garden margins of the older properties on the village edge toward Nant Peris.
