Typical swarm locations
Collectors attend swarms in the village terrace streets and industrial estate periphery, on gorse scrub and bilberry heath above the Hirwaun plateau, in the hawthorn and sycamore hedgerows on the lanes toward Penderyn and Penywaun, in allotments and cottage gardens in the settlement, and in dry-stone wall cavities on the open moorland above Hirwaun Common.
