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.
Sphecius grandis
"Sphecius grandis" wasps frequently interact with humans because of their tendency to make their nests in backyards, gardens and sidewalks. Pest control is mostly unneeded as they nest in areas with little to no vegetation, usually ignore people, and females are not aggressive, tending to save their venom for their cicada prey, but will sting if they are grabbed or stepped on. Despite their large size, being the largest wasp to inhabit California, their sting has been reported as being between merely numbing and sharp to moderate. Males, while smaller, are naturally more aggressive and less tolerant of disturbance.
