Two alarming weather related stories today. First we have the alarming news that Asian hornets have arrived in the UK, previously it was thought too cold for them here but apparently no one told the hornets. This rather scary looking predator has a penchant for decapitating honey bees, and poor old European bees haven't yet evolved any natural defense against these killers. Japanese bees have learned to swarm onto attacking hornets, vibrating their bodies against them, causing an overheat. Even so, a swarm of hornets can pretty much wipe out a bee colony by sheer blunt force of size and power.
