Typical swarm locations
Collectors attend swarms on the old riverside terrace eaves and harbour-side garden walls of Bank Place and Underbanks, in the Avon riverside willow and alder scrub at Pill Creek and Ham Green, in the orchard and walled garden remnants of Ham Green village, and in the hawthorn hedgerows of the Gordano Valley lane network between Pill and Easton-in-Gordano.
