''Polistes instabilis'', a type of paper wasp, is a neotropical, eusocial wasp (family Vespidae) that can be found in tropical and subtropical areas such as Central America and South America.〔(【引用サイトリンク】title=Polistes Instabilis )〕 It can be easily identified with its characteristic yellow, brown, and reddish markings, and it builds nests made from chewing plant fibers and making them into paper. Colonies are usually initiated in the spring after the foundresses have emerged from the winter. Either one or a few queens found each colony by laying eggs, which develop into workers. Although there are no morphological differences between queens and workers, queens can be identified easily by their dominant interactions with workers. While queens are responsible for laying eggs, workers are responsible for gathering materials for the nest, tending to the young, and foraging for food. This species tends to feed on nectar as well as arthropods such as caterpillars. ==Description and Identification==

Body size ranges between with wings that are about , which are folded longitudinally against the body.〔 Male ''Polistes'' are typically smaller than females, have a yellow face, and hold their antenna curled at the tips, while females hold their antenna straight at the tips and have more dark markings on their faces.〔 Nests are constructed with paper substance made by chewing up plant fibers, and they are typically connected a surface by a stalk.〔〔 The cells of the nest are not covered as they are in some other wasp species.〔
