Typical swarm locations
Collectors regularly attend swarms along the Frome Valley Walkway willows and watermeadow margins from Snuff Mills to Oldbury Court, in the older garden and orchard remnants of the Lodge Causeway and Downend Road residential belt, on the bramble and scrub of the Staple Hill Railway Path, and in the chimney stacks and eaves of the older Edwardian and Victorian terraces around Fishponds Road.
