Polistes is a cosmopolitan genus of paper wasps and the only genus in the tribe Polistini. Vernacular names for the genus include umbrella wasps, coined by Walter Ebeling in 1975 to distinguish it from other types of paper wasp, in reference to the form of their nests, and umbrella paper wasps. Polistes is the single largest genus within the family Vespidae, with over 200 recognized species. Their innate preferences for nest-building sites leads them to commonly build nests on human habitation, where they can be very unwelcome; although generally not aggressive, they can be provoked into defending their nests. All species are predatory, and they may consume large numbers of caterpillars, in which respect they are generally considered beneficial.
Pison is a cosmopolitan genus of wasps within the family Crabronidae. The genus comprises 145 described species, although many species, especially in South America remain undescribed.
Larra, also known as mole cricket wasps or mole cricket hunters, is a genus of wasps that prey on various species of mole crickets. They have gained prominence as integrated pest management agents.
Ropalidia is a large genus of eusocial paper wasps (Polistinae) in the tribe Ropalidiini distributed throughout the Afrotropical, Indomalayan and Australasian biogeographical regions. The genus Ropalidia is unusual because it contains both independent and swarm-founding species. Ropalidia romandi is one of the swarm founding species, meaning that new nests are founded by a large group of workers with a smaller number of inseminated females, while Ropalidia revolutionalis is independent-founding, meaning that each nest is founded by a single foundress.
Thyreus is an Old World genus of bees, one of many that are commonly known as cuckoo bees, or cloak-and-dagger bees, and are kleptoparasites of other species of bees, mostly in the genus Amegilla. They all have strongly contrasting patterns of coloration – three species from the Sydney region, Thyreus nitidulus, T. lugubris, and T. caeruleopunctatus are bright blue and black.
Rhynchium is an Australian, Afrotropical, Indomalayan and Palearctic genus of potter wasps.
Episyron is a genus of wasps in the family Pompilidae which prey on spiders. Nine species are found in Europe.
The Pompilinae are a subfamily of the spider wasp family, Pompilidae, the species of which lay their eggs on the paralyzed bodies of their prey.
Auplopus is a large genus of spider wasps belonging to the subfamily Pepsinae of the spider wasp family Pompilidae, distributed throughout the world except for Antarctica. Auplopus wasps amputate the legs of their spider prey before transporting it to the nest.
Evagetes is a genus of spider wasps from the family Pompilidae. There are 72 described species, of which 58 are found in the Palaearctic region, 11 in the Nearctic region, with a few penetrating to the Afrotropical, Oriental and Neotropic regions. Evagetes wasps are kleptoparasitic on other pompilid wasps, especially the genera Arachnospila, Anoplius, Episyron and Pompilus, digging into their sealed burrows, eating the host egg and replacing it with an egg of its own. Evagetes wasps are characterised by their very short antennae. Most are species are black with the base of the antennae rufous, several Evagetes species are very metallic bluish insects.
Pterocheilus is an essentially holarctic genus of potter wasps with a fairly rich diversity in North America and a single Afrotropical species Pterocheilus eurystomus Kohl 1906 known from Socotra. They are usually rather large wasps characterized by reduced tegulae and prominently pilose labial palpi.
Hemipepsis is a genus of large pepsine spider wasps found throughout the tropics. They are commonly known as tarantula hawks. Hemipepsis wasps are morphologically similar to the related genera Pepsis and Entypus, but distinguishable by the pattern of wing venation. In South Africa 18 plant species from three plant families, the Apocynaceae, Orchidaceae, and Asparagaceae subfamily Scilloideae are pollinated exclusively by Hemipepsis wasps.
Dryudella is a genus of wasps in the family Crabronidae. There are more than 50 described species in Dryudella.
Ferreola is a genus of wasps belonging to the family Pompilidae.
