Typical swarm locations
Collectors in Hoddesdon regularly attend swarms in the mature sycamore and lime of Pound Close Park and the older residential streets near the Market Hoddesdon Cross, along the Lee Navigation riverside willows and alder scrub between Rye House and Dobbs Weir, in the nursery and allotment garden margins south of the town, and in the chimney stacks and garden eaves of the Victorian and Edwardian townhouses near the town centre.
