Some wasps are even parasitoids of parasitoids; the eggs of Euceros are laid beside lepidopteran larvae and the wasp larvae feed temporarily on their haemolymph, but if a parasitoid emerges from the host, the hyperparasites continue their life cycle inside the parasitoid. [19] Parasitoids maintain their extreme diversity through narrow specialism.
In all, perhaps 700,000 or so parasitoid wasp species are estimated to exist, but it’s probable that the number is far higher. Even the parasitoids are not immune to victimization.
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps being in the wasp-waisted Apocrita. As parasitoids , they lay their eggs on or in the bodies of other arthropods , sooner or later causing the death of these hosts .
Apocrita (wasps, bees and ants) Hymenoptera is a large order of insects , comprising the sawflies , wasps , bees , and ants . Over 150,000 living species of Hymenoptera have been described, [ 2 ] [ 3 ] in addition to over 2,000 extinct ones. [ 4 ]

They tend to be less conspicuous than the social (wasps) do,” Kimsey said, adding that they are “good to have around” to eat other bugs such as caterpillars. There are roughly 300 species of ...
Charles Darwin considered the evolution of eusociality a major problem for his theory of natural selection.In The Origin of Species, he described the existence of sterile worker castes in the social insects as "the one special difficulty, which at first appeared to me insuperable and actually fatal to my whole theory".
Also, a related genus of Asian nocturnal vespines, Provespa, is referred to as "night wasps" or "night hornets", [5] though they are not true hornets. [6] Some other large wasps are sometimes referred to as hornets, most notably the bald-faced hornet (Dolichovespula maculata) found in North America. It is set apart by its black and ivory ...
