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.

In the wild probably the most important insect enemy of "Kotochalia junodi" is an interesting parasitoid wasp, a member of the Ichneumonidae, "Sericopimpla sericata". In colour the wasp is largely black, yellowish, and red. The female wasp is about 12 mm in length, and like many Ichneumonids she has a protruding ovipositor almost as long as her gaster.
