[1] [2] Additionally, because R. romandi is a paper wasp, it has the ability to repeatedly sting without dying. [11] R. romandi is most aggressive if they are swarming, [9] if their nests are disturbed or if the wasps feel their nest is threatened. [12] If wasps feel threatened, they may swarm out of the nest, and pursue the aggressor. [12]
Paper wasp (Polistes major) nest (); exposed comb Paper wasp growth stages Yellowjacket nest (); concealed combPaper wasps are a type of vespid wasps.The term is typically used to refer to members of the vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae (hornets and yellowjackets) and Stenogastrinae, which also make nests out of paper.
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]
Some wasps tend to be more aggressive than others, though: Paper wasps, yellowjackets, and bald-faced hornets pose more serious stinging hazards while mud-daubers aren’t as aggressive. (But ...

P. metricus, female. 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, [3] and umbrella paper wasps.

Polistes apachus is a social wasp native to western North America. [2] It is known in English by the common name Texas paper wasp, [3] [4] or southwestern Texas paper wasp. [5] It has also been called the Apache wasp, perhaps first by Simmons et al. in California in 1948.
Paper wasps on the other hand, have only workers and foundresses who defend the nest together. [20] The foundress is the most aggressive defender of the nest since she has the most reproductive investment. [21] In some cases, Polistes fuscatus has been shown to share nests with a closely related species, Polistes metricus. [22]
