Wasp
The largest social wasp is the Asian giant hornet, at up to in length. The various tarantula hawk wasps are of a similar size and can overpower a spider many times its own weight, and move it to its burrow, with a sting that is excruciatingly painful to humans. The solitary giant scoliid, "Megascolia procer", with a wingspan of 11.5 cm, has subspecies in Sumatra and Java; it is a parasitoid of the Atlas beetle "Chalcosoma atlas". The female giant ichneumon wasp "Megarhyssa macrurus" is long including its very long but slender ovipositor which is used for boring into wood and inserting eggs. The smallest wasps are solitary chalcid wasps in the family Mymaridae, including the world's smallest known insect, "Dicopomorpha echmepterygis" (139 micrometres long) and "Kikiki huna" with a body length of only 158 micrometres, the smallest known flying insect.
Wasp (comics)
Making use of the cellular implantation of sub-atomic Pym particles, the Wasp possesses the power to alter her physical size, causing her body's mass to be shunted to or gained from an alternate dimension known as Kosmos. She is able to shrink to a minimum of several centimeters or grow to a maximum of several hundred feet. Smaller or larger sizes are possible but the exertion puts a strain on her body. Initially, these abilities stem from use of a Pym particle gas released from special capsules, and later biochemical augmentation by Henry Pym. Over time, however, her body absorbs enough particles to cause cellular mutation due to repeated exposure to Pym particles, allowing her to alter her size at will.
