Wasp
Wasps first appeared in the fossil record in the Jurassic, and diversified into many surviving superfamilies by the Cretaceous. They are a successful and diverse group of insects with tens of thousands of described species; wasps have spread to all parts of the world except for the polar regions. The largest social wasp is the Asian giant hornet, at up to in length; among the largest solitary wasps is a group of species known as tarantula hawks, along with the giant scoliid of Indonesia ("Megascolia procer"). The smallest wasps are solitary chalcid wasps in the family Mymaridae, including the world's smallest known insect, with a body length of only , and the smallest known flying insect, only long.

Their most dangerous predator is the pepsis wasp, commonly called the tarantula hawk. Locally it is known as a "matacacata" (the tarantula-killer). This is a very large parasitoid wasp, with an iridescent blue-green body and orange-red wings that grows to about 2 inches or more in length. It captures the spider in its burrow or sometimes in the open and stings it to paralyze it and then lays its eggs on the abdomen. The wasp will drag its victim to a safe place to incubate its young. Once the larvae hatch they will feed on the alive but paralyzed tarantula until it dies.
