Chalybion is a genus of blue mud dauber wasps in the family Sphecidae. Chalybion species nest in a wide range of natural and artificial cavities such as holes in wood, walls, plant stems, etc., where they typically provision their brood cells with paralyzed spiders. They also reuse old nests of other wasps like Trypoxylon and Sceliphron. [1]
The European paper wasp (Polistes dominula) is one of the most common and well-known species of social wasps in the genus Polistes.Its diet is more diverse than those of most Polistes species—many genera of insects versus mainly caterpillars in other Polistes—giving it superior survivability compared to other wasp species during a shortage of resources.
Approximately 300 species of Polistes paper wasps have been identified worldwide. The most common paper wasp in Europe is Polistes dominula. [2] The Old World tribe Ropalidiini contains another 300 species, and the Neotropical tribes Epiponini and Mischocyttarini each contain over 250 more, so the total number of true paper wasps worldwide is about 1100 species, almost half of which can be ...
Ground wasps, or yellowjackets, are about ½-inch long with alternating black and yellow bands on the abdomen. They don’t carry pollen like honeybees do in pollen baskets on their rear legs.
Polistes humilis is in the genus Polistes, which consists of 150 species that can be found in all regions except the world's coldest climates. Polistes humilis was the only species of the tribe Polistini found in New Zealand after it was accidentally introduced from Australia, [4] prior to the introduction of the Asian paper wasp, Polistes chinensis in 1979.

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 ...
Several wasps build a nest to lay their eggs. Hot weather could increase the number of wasps in California. ... Several wasps feed on Queen’s Anne lace plants on June 29, 2012, in Davis ...
The different species of wasps were seen to coexist without conflict. The evolutionary significance of joint nesting is unclear. Proposed hypotheses include the fact that it might represent the beginning stages of interspecific mutualism or exploitation. [6] Nest reuse has been observed in Polistes metricus species. It is common for a foundress ...
