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.
Polistes snelleni
"P. snelleni" are black and yellow wasps. The queens are the biggest of the species, and the workers, young queens, and males follow. Workers typically have worn wings that distinguish them from young queens. The weight of new reproductive females (young queens) is 102 mg. Workers can be identified by white-creamy body fat. Workers that have developed ovaries are workers, but not reproductive females.
