Typical swarm locations
Hawthorn and elder on the Cottingham Road field-boundary hedgerows approaching the East Riding boundary are a reliable late-April swarm site. Inter-war residential garden sycamore and ornamental cherry in Hall Road and Calvert Lane attract clusters through May and June. Chimney stacks and roof voids of the 1930s-50s semi-detached housing are regularly reported as cavity swarm locations. Elder on the Anlaby Park Road scrub margins near the sports ground produces swarms in late May.
