The description of barbed or unbarbed is not precise: there are barbs on the stings of yellowjacket wasps and the Mexican honey wasp, but the barbs are so small that the wasp can sometimes withdraw its sting apparatus from victim's skin. [7] The stings of some wasps, such as those of the Polistes versicolor, contain relatively large amounts of ...
Wasp stinger, with droplet of venom Under natural conditions, orb-weaving spiders ( Argiope spp.) undergo autotomy (self-amputation) if they are stung in a leg by wasps or bees. Under experimental conditions, when spiders were injected in the leg with bee or wasp venom, they shed this appendage.
As with other wasps, death due to a single sting on the skin only occurs when an allergy is present, and serious outcomes with Asian giant hornet stings in China and Japan are only documented with many stings or anaphylactic shock due to an existing allergy. [12] People who are allergic to wasp venom may also be allergic to hornet stings.
Typically, paper wasps are relatively unaggressive, only attacking humans and animals if they or their nests are being threatened. As in other aculeate wasps, only females have the ability to sting. [16] Unlike bees, wasps do not have barbed stingers that can be lost, so they are able to sting multiple times to defend a nest. [17]
Males have wings but lack a stinger. Females are 2–5 mm long; they have a stinger but lack wings. They are black/brown, and have the appearance of ants. Females enter woodworm holes, paralyze the woodworm larvae with the venom of the stinger and lay their eggs in the corpses, which form the food for the S. domesticus larvae. This behavior ...

Synoeca septentrionalis is one of five species of wasps in the genus Synoeca. [1] It is a swarm-founding wasp that is also eusocial, [2] exhibiting complicated nest structure and defense mechanisms [3] and a colony cycle including a pre-emergence phase and a post-emergence phase. [4]
Chrysis ignita is a species of cuckoo wasp.It is one of a group of species which are difficult to separate and which may be referred to as ruby-tailed wasps.. Cuckoo wasps are parasitoids and kleptoparasites, laying their eggs in the nests of other species where their young consume the larvae of their hosts.
