Parasitic wasps dive-bomb ants, injecting their eggs into ant bodies. Soon the ant dies, its body converted into an egg-producing factory.
Four wasp species performed the aerial trick on camera for José María Gómez Durán of Madrid. Two are new to science and were described August 26 in ZooKeys by Kees van Achterberg, a naturalist from the Netherlands Centre for Biodiversity.
Some of the wasps deposit their eggs into adult ants, others into ant larvae. Ants are well-equipped to defend their nests, however, so biologists still aren’t sure how young wasps survive inside the nests. It’s possible that dead ants are carried outside, allowing the hatching wasps to escape.
