Beewolf
Beewolves (genus Philanthus), also known as bee-hunters or bee-killer wasps, are solitary, predatory wasps, most of which prey on bees, hence their common name. The adult females dig tunnels in the ground for nesting, while the territorial males mark twigs and other objects with pheromones to claim the territory from competing males.

"V. mandarinia" is the only species of social wasp known to apply a scent to direct its colony to a food source. The wasp secretes the chemical from the sixth sternal gland, also known as van der Vecht's gland. This behavior is observed during autumnal raids after the hornets begin hunting in groups instead of individually. The ability to apply scents may have arisen because the wasp relies heavily on honeybee colonies as its main food source. A single wasp is unable to take on an entire colony of bees because species such as "Apis cerana" have a well-organized defense mechanism. Honeybees swarm one wasp and flutter their wings to heat up the wasp and raise carbon dioxide to a lethal level. So, organized attacks are much more effective and easily devastate a colony of tens of thousands of honeybees.
