Typical swarm locations
Collectors attend swarms in the mature lime trees and sycamores of Birtley Cemetery and the older residential streets near St Joseph's church, in the bramble and willowherb banks of the reclaimed colliery and brick-works margins, in the allotment hedges and compost areas of the Birtley and Pelton gardens, and in the garden eaves and chimney pots of the Victorian terraces of Durham Road and Drum Road.
