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.
Tarantula
Regardless of their fearsome reputation, tarantulas themselves are an object of predation. The most specialized of these predators are large members of the wasp family Pompilidae such as the wasp "Hemipepsis ustulata". These wasps are called "tarantula hawks". The largest tarantula hawks, such as those in the genus "Pepsis", track, attack, and kill large tarantulas. They use olfaction to find the lair of a tarantula. The wasp must deliver a sting to the underside of the spider's cephalothorax, exploiting the thin membrane between the basal leg segments. This paralyzes the spider, and the wasp then drags it back into its burrow before depositing an egg on the prey's abdomen. The wasp then seals the spider in its burrow and flies off to search for more hosts. The wasp larva hatches and feeds on the spider's inessential parts and, as it approaches pupation, it consumes the remainder. Other arthropods, such as giant centipedes, are also known to prey on tarantulas.
