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.
Aphomia sociella
The bee moth is a pest of bumblebees, wasps, and on rare occasions even mice. Females prefer to lay their eggs in more exposed and elevated nests of various species of "Bombus" and "Vespine" wasps. It is uncommon for a bee moth to seek out nests that are closer to the ground. Because this moth is able to hide its eggs in these foreign nests, she does not have to devote any energy to parental care.
