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.
Hymenoptera training
Sniffer bees or sniffer wasps are insects in the order Hymenoptera that can be trained to perform a variety of tasks to detect substances such as explosive materials or illegal drugs, as well as some human and plant diseases. The sensitivity of the olfactory senses of bees and wasps in particular have been shown to rival the abilities of sniffer dogs, though they can only be trained to detect a single scent each.
