I had the luck to watch the most amazing sight yesterday. A European hornet (and these are huge... this one was over an inch long and stocky) flew over and alit on the side of the hive. The girls went about their business. Then the hornet flew over to the entrance, and before I knew it a honeybee dove in from the left and knocked that hornet off the hive like a football player tackling a quarterback and knocking him right out of the picture on the TV screen. The hornet tried to fly off, but the bee was firmly holding on, stinging repeatedly. The hornet eventually flew off awkwardly, with bee still attached. Atta girl!
