Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Little Germany and Manningham conservation areas, on the heather and bilberry moorland margins of Baildon Moor and Rombalds Moor above Ilkley, along the Aire and Bradford Beck riverside willows at Saltaire and Hirst Wood, and in the chimney stacks and eaves of the older Victorian wool-city properties.
