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.
Crematogaster
Acrobat ants are known to eat different types of wasps. Many of these wasps have mutualistic relationships with trees involving pollination. Additionally, the wasps typically have cycles which they follow, which can make it difficult for them to be located and captured by the ants. As a result, acrobat ants have evolved unique characteristics to detect the presence of prey. They have become sensitive to chemical signals that are released by wasps and use these signals as cues in the location of their prey.
