Typical swarm locations
Collectors attend swarms on the garden walls and eaves of the terraced streets along White Rose Way and Commercial Street, along the Rhymney River bank and its elder, bramble and willowherb margins, in the bilberry and hawthorn scrub on the valley sides above the town, in the churchyard and chapelyard trees, and in the gorse scrub on the moorland approaches to Cefn Hengoed ridge.
