Typical swarm locations
Collectors attend swarms along the River Bann willow and alder margins north and south of the town, in the hawthorn hedgerows on the drumlin farm lanes toward Garvagh and Ahoghill, at the sycamore and ornamental trees around the Diamond and Church Street, along the Agivey Water margins north of the town, and in the eaves and roof voids of older village properties near the market square.
