Typical swarm locations
Collectors attend swarms in the hawthorn and elder scrub on the Wombwell Woods valley margins, along the Dearne floodplain willow and reed-bed edges at Old Moor and Manvers Lake, on the eaves and chimney pots of the older mining-town terraces around High Street and Station Road, and in the garden boundaries and sycamore trees of the residential streets above the valley.
