Bees, wasps and ants

The YNU's Recorder for bees, wasps and ants is Dr Andy Millard (editor@ynu.org.uk), who took over following the retirement of Dr Michael Archer at the Entomological Section AGM in 2019. Dr Archer, a distinguished researcher in the field, had been recorder for 32 years, and has amassed over 33,000 records.  A PDF version of his Characteristics and Life-Histories of Yorkshire Aculeates is available to download here.

 

Bees, Wasps and Ants (known collectively as aculeates) belong to the Order Hymenoptera, which also includes sawflies and parasitic wasps. Aculeates have a narrow ‘waist’, also characteristic of parasitic wasps. However, the latter have ovipositors whereas in aculeates the equivalent structure has evolved into a sting. Some aculeates are relatively easy to identify in the field but many are not, so, when submitting records, good quality photos of the insect (ideally taken from several angles!) are very welcome, as are any specimens.

 

All records are sent to the national recording scheme, run by the Bees, Wasps and Ants Recording Society (BWARS), who make the data publicly available via the NBN Atlas. BWARS has an excellent website with information on all the aculeate species currently recorded in the UK.
