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.
Mischocyttarus drewseni
"M. drewseni" is a member of the family Vespidae, which is broken down into four subfamilies: paper wasps (subfamily Polistinae), pollen wasps (subfamily Masarinae), potter and mason wasps (subfamily Eumeninae), and yellow jackets (subfamily Vespinae). Within the Vespidae, "M. drewseni" belongs to the subfamily Polistinae which is typically found in tropical regions and comprises 25 genera. Within the Polistinae is the tribe Epiponini containing many genera, all of which, including "M. drewseni", are found in the New World. The asymmetrical tarsal lobes of the genus "Mischocyttarus" separates it from other Epiponini. "Mischocyttarus" larvae also have distinct first thoracic spiracles. "Mischocyttarus" is the largest genus of social wasps, containing 186 species.
