Typical swarm locations
Collectors attend swarms in the Rumney Valley Local Nature Reserve scrub and bramble margins, along the Rumney River path and its alder, elder and willow banks, on the garden walls and eaves of the residential streets off Llanrumney Avenue and Ball Road, in the playing field hedgerow remnants, and in the elder and hawthorn scrub at the settlement edge where housing meets the remaining farmland.
