Adoption is a result of three situations: when queens lose their nests and "make the best of a bad situation"; workers leave multiple-foundress nests; and subordinates employ a "sit-and-wait" strategy, waiting for nests to be abandoned. Nests are orphaned when the adult wasps die while taking care of their nest, leaving an immature brood.
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.
All species of social wasps construct their nests using some form of plant fiber (mostly wood pulp) as the primary material, though this can be supplemented with mud, plant secretions (e.g., resin), and secretions from the wasps themselves; multiple fibrous brood cells are constructed, arranged in a honeycombed pattern, and often surrounded by ...
Wasps are looking for large bodies of water such as pools and ponds to cool themselves down, “which makes them seem more present” compared to past years, Kimsey told The Sacramento Bee.
Since the nests are single combs fixed to a substrate by a peduncle, the suspended cells are often protected from attack by ants. [6] If there is an ant attack, nest abandonment is easier and allows for a more rapid escape due to the fact that the wasps do not build envelopes over their nests.
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.

Females can build their own nests, but often refurbish nests abandoned by other wasps and bees, [4] particularly those of Sceliphron caementarium, [5] removing any spiders captured by S. caementarium and the larva, replacing it with an egg of its own and freshly caught spiders. [3] They go through multiple generations in a year. [2]
