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.
Wasp (comics)
During their invasion of America, the Liberators fail to take Wasp into account, discounting her as being no threat due to her abilities being those to make herself "smaller and weaker". Janet is able to make her way to the cells in the Triskelion where Captain America is being held under suspicion of the murder of Hawkeye's entire family. Though she is discovered and apparently subdued, she has already liberated her boyfriend. Though Captain America easily beats the Schizoid Man, he stops fighting when several super soldiers threaten to tear Wasp apart; she then surprises them all by using her stinging powers at her normal size for the first time, killing or incapacitating all the super soldiers at once. At some point, Hank gives Janet a dose of the Giant-Man serum, which allows her to grow to gigantic proportions. At a larger size, Janet helps turn the tide in favor of American forces and crushes the Insect Queen with one stomp of her foot. It is unknown whether she can grow at will or whether this is a one-off experience.
