European Hornet Movie

From the video's description: The European hornets, Vespa crabro, have a worker caste and form annual colonies which last for just one summer. In the video one can see workers active around their nest entrance in a hollow tree. Hornets are capable of fanning their wings like bees to cause a draught, or movement of air, for cooling the nest or evaporating moisture from the larvae. They prey on many types of insects, particularly on caterpillars, although hornets are attracted to meat and sweet drinks. Their painful stinging ability causes alarm and fear.
But it is sensible to leave hornet nests undisturbed in order to encourage the natural control of pests. More importantly it will help protect wildlife.

Sting prevention:
Don't get closer to a colony than 3 meters (9 ft.)!
And what is more important avoid blocking their flight path and slapping against these insects.
One sting does cause pain no longer than a sleepless night lasts. So there's enough time cooling the area around the sting to get a wonderful and completely unique experience.
