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.
Polybia sericea
When workers hunt for arthropods, they fly from side to side about half a meter off of the ground. Visual cues are used to determine where to search for prey, whereas olfactory cues are used to determine that prey is near, and elicit landing. Green and brown caterpillars are the most common prey for "P. sericea". Once a caterpillar or other insect has been found, workers bite the insect behind the head. They will then drag the prey up onto a twig or a piece of grass, or will sometimes fly the insect to a different location; they do this in order to keep ants or other insects from stealing their prey. Once the insect is in a safe location, the wasp will malaxate the prey, or soften it by mixing it with a thinner substance, presumably saliva. The worker will then bring what it can back to the nest to feed other individuals. If prey is too large to bring back to the nest, foragers will leave the prey, and fly in side to side arcs back to the nest to recruit other workers to help carry the load.
