Typical swarm locations
Collectors attend swarms in the older stone properties and farm buildings of Sennybridge village, along the River Usk bankside willows and elder scrub toward Trecastle, on the Mynydd Epynt heather and bilberry moorland fringe, in the hawthorn and whin hedgerows of the lower Epynt slopes, and in the Usk valley meadow margins and walled farmyards between Sennybridge and Defynnog.
