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.
Hunting wasp
Hunting wasps are members of various taxa of the insect order Hymenoptera. Their habits and affinities vary in many ways, but all practise parental care of their larvae in that they capture prey, usually insects, to feed their larvae. Whether solitary or social, most species construct some form of protection or nest in which they hide the prey and in which the larvae can feed and pupate in reasonable security.
