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.
At lower elevations, the nests are located in deciduous and hard evergreens, and at higher elevations in conifers. Nests are typically found within 50 meters of rivers. [1] M. flavitarsis is also known to nest in the built environment, particularly in protected spaces such as wall voids, the underside of eaves, etc.
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 ...

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.
Vespula rufa, commonly known as the red wasp, [3] is a social wasp species belonging to the genus Vespula.It is found in northern and central Europe and parts of Asia. [4] [5] Vespula rufa is characterised by red-brown markings and body segmentation, with the appearance varying amongst the different roles of individuals in the species. [6]
Wasps that build their nests on the underside of leaves will add an ant guard to the stem to prevent ants from attacking the nest. [2] Ant guard construction is a behavior peculiar to P. jacobsoni among its genus, although it does occur in some wasps in the genera Eustenogaster and Liostenogaster via a radically different behavioral mechanism ...
