Typical swarm locations
Collectors attend swarms along the willow and alder bankside of the Blackwater River and its drainage channels through the valley, in the whitethorn and blackthorn hedgerows on the drumlin farm lanes toward Clogher and Fivemiletown, on the gorse and heather of the Roughan Hill moorland fringe above the village, and in the eaves and ivy-covered walls of older cottages throughout.
