Typical swarm locations
Local collectors attend swarms in the riverside willows and hawthorn scrub along the Derwent at the weir and viaduct, in the lime and sycamore trees of the village centre near St John's church, in the garden eaves and chimney stacks of the older properties on the Pocklington Road and Main Street, and in hedgerow oaks and field margins on the Vale farmland toward Gate Helmsley and Full Sutton.
