In this episode I'm Hive Talkin with Prof. David Evans AKA The Apiarist Blog as we attempt to understand what a honeybee swarm is, why it happens, how it happens and how we can all benefit from this amazing (and harmless) spectacular of nature.

David is a Scottish based beekeeper and professor of virology currently at St Andrews University.  His research interests include the replication and evolution of important human and animal viral pathogens including Poliovirus, HIV, Zika virus and both Deformed Wing Virus  and Chronic Bee Paralysis Virus of honeybees.

You can follow David on twitter @the_apiarist or visit his entertaining and informative blog www.theapiarist.org which is stuffed full of timely and detailed advice laced with more than a touch of humour.
