Typical swarm locations
Collectors regularly attend swarms in the lime trees and old walled gardens of the King's Parade and Hills Road conservation areas, along the Cam riverside willows and watermeadow margins at Grantchester Meadows and the Backs, on the chalk grassland and scrub margins of the Gog Magog Hills, and in the chimney stacks and eaves of the older university and Victorian city-centre properties.
