''Protopolybia exigua'' is a species of vespid wasp found in South America and Southern Brazil.〔Noll,Fernando B. "Morphological Caste Differences in Neotropical Swarm-FoundingPolistinae Wasps. V-Protopolybia Exigua Exigua (Hymenoptera: Vespidae)." ''Journal of the New York Entomological Society'' 104.1/2 (1996): 62-69. ''JSTOR''. Web. 〕 These neotropical wasps, of the tribe Epiponini, form large colonies with multiple queens per colony. ''P. exigua'' are small wasps that find nourishment from nectar and prey on arthropods.〔Gastreich, K. R., J. E. Strassman, and D. C. Queller. "Determinants of High Genetic Relatedness in the Swarm-founding Wasp, Protopolybia-exigua." ''Ethology, Ecology & Evolution'' 5.4 (1993): 529-39. Print. 〕〔Rocha, AA, and Carlos Costa Bichara Filho. "Resources Taken to the Nest by Protopolybia Exigua (Hymenoptera, Vespidae) in Different Phases of the Colony Cycle, in a Region of the Medio Sao Fransisco River, Bahia, Brazil." ''Sociobiology ''54.2 (2009): 439-56. Print.〕 Their nests are disc-shaped and hang from the undersides of leaves and tree branches.〔 This particular species of wasp can be hard to study because they frequently abandon their nests.〔Souza, A. R. De, D. De F. A. Venancio, F. Prezoto, and J. C. Zanuncio. "SOCIAL WASPS (HYMENOPTERA: VESPIDAE) NESTING IN EUCALYPTUS PLANTATIONS IN MINAS GERAIS, BRAZIL." ''The Florida Entomologist'' 95.4 (2012): 1000-002. ''JSTOR''. Web. 〕 ''P. exigua'' continuously seek refuge from phorid fly attacks and thus often flee infested nests to build new ones. The wasps’ most common predators are ants and the parasitoid phorid flies from the Phoridae family.〔Simones, Dercio, Fernando B. Noll, and Ronaldo Zucchi.

Print.〕 == Taxonomy and Phylogeny == The Epiponini belong to the swarm-founding wasp subfamily Polistinae.〔Noll, F. B., and R. Zucchi.
