Polistes Penthicus Penthicus
''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. Description As part of subfamily Polistinae, ''Polistes'' wasps are covered in short and inconspicuous hair, have a clypeus with a pointed apex, have a gena that is wide throughout, tergum 1 of the metasoma is almost straight t ...

Polistes Gallicus
''Polistes gallicus'' is a species of paper wasp found in various parts of Europe, excluding England, Denmark, and Scandinavia, from warmer climates to cooler regions north of the Alps. Nests of these social insects are created in these various conditions. The ''Polistes'' species use an oral secretion to construct their nests, which consist of a combination of saliva and chewed plant fibers. This structural mixture physically protects the nest from various harsh elements and from weathering over time. Description and identification ''P. gallicus'', like other members of the subgenus ''Polistes (Polistes)'', has recognizable, bright yellow and black markings. They have smaller bodies than many of its allies that overlap in range, and their bodies are largely hairless. The species may be separated from allies through the following traits. Females are identified by having 12 antennal segments and 6 abdominal segments. The antennae are orange and paler on the ventral surface than i ...
