In some species, the larvae are predatory themselves; the wasp eggs are deposited in clusters of eggs laid by other insects, and these are then consumed by the developing wasp larvae. [ 10 ] The largest social wasp is the Asian giant hornet , at up to 5 centimetres (2.0 in) in length. [ 11 ]
The female wasp may then engage in spreading soil or other changes to the area, leaving the nest site inconspicuous. One species of spider wasp protects its nests by putting dead ants into the outermost chamber, where the ants' chemicals deter predators. [16] [17] Wasp dragging a spider to its nest
Some attack arthropods other than insects: for instance, the Pompilidae specialise in catching spiders: these are quick and dangerous prey, often as large as the wasp itself, but the spider wasp is quicker, swiftly stinging her prey to immobilise it. Adult female wasps of most species oviposit into their hosts' bodies or eggs.
The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, [ 2 ] while others are notable predators of pest ...
The winged insects fall into the order Hymenoptera, which includes bees and ants. Wasps come in a variety of colors — from yellow and black to red and blue — and are split into two primary ...
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas.Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host.

Many of the insects collected by the workers are considered pest species, making the yellowjacket beneficial to agriculture. [4] Larvae, in return, secrete a sugary substance for workers to eat; this exchange is a form of trophallaxis. As insect sources of food diminish in late summer, larvae produce less for workers to eat.
