These giant wasps love the Lilac bush at this time of year because of seeping syrup from the bush. First the Cicada Killer is seen slurping syrup and then a European Hornet swoops in to oust the Cicada Killer. Interestingly, the Cicada Killer's sting is said to be as mild as a sweat bee's, but the European Hornet's is quite another matter with stings being quite severe. Filmed at a somewhat safe distance. Note the house flies not wanting to give up their share either. Pretty brave little guys.
