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").

Hyalophora cecropia
Hyalophora cecropia, the cecropia moth, is North America's largest native moth. It is a member of the family Saturniidae, or giant silk moths. Females have been documented with a wingspan of five to seven inches (160 mm) or more. These moths can be found all across North America as far west as Washington and north into the majority of Canadian provinces. Cecropia moth larvae are most commonly found on maple trees, but they have also been found on cherry and birch trees among many others. The species was first described by Carl Linnaeus in his 1758 10th edition of "Systema Naturae"
