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 ...

C. brunnea has a triangular head with large, compound eyes and a broad frons. [1] It has straight antennae. Its raptorial forelegs are similar in shape and function to that of Mantodea; this adaptation has evolved independently in the two groups and is an example of convergent evolution. [2]
Synoeca septentrionalis exhibits a blackish or dark blue color and has a metallic-like appearance. [1] Their wings are also quite large and are entirely infuscate. [1] Their metasomal tergum (a portion of the abdomen) and sternum both exhibit erect hairs, and their clypeus is imprinted with an area that resembles a dark triangle. [1]
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]
A European hornet stinger under an optical microscope. Hornets have stingers used to kill prey and defend nests. Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. [8] [9] Individual hornets can sting repeatedly.
Another wasp, Pachysomoides fulvus, is an ectoparasitoid of Polistes apachus [8] and other paper wasps in the United States. Pachysomoides fulvus lays eggs on the larvae of Polistes apachus . This especially affects new nests with only one foundress, as the queen must therefore leave the nest to find food.
The mammoth wasp resembles a very large, elongated bumble bee. The female is larger than the male and has a yellow head, the male has a black head. Its body is covered in downy hair and is glossy black in colour with two yellow bands across its abdomen which are sometimes divided to form four yellow spots. [ 2 ]
