Typical swarm locations
Collectors attend swarms in the ivy-clad castle ruins and the old garden walls of the conservation area around Earsham Street and Staithe Road, along the riverside willow and alder on the Outney Common and Bigod Castle loop, in the old orchard and cottage gardens of the outlying villages of Ditchingham and Ellingham, and in the chimney pots and old lime-pointed walls of the market-place properties.
