Typical swarm locations
Collectors attend swarms in the lime and sycamore parkland of the Montalto estate, along the Ballynahinch River willows and balsam banks, in the deep whitethorn and blackthorn hedgerows on drumlin farm lanes north toward Saintfield and south toward the Mournes foothills, and in ivy-covered stone walls and outbuildings on the older farm steadings.
