Protopolybia exigua is a species of vespid wasp found in South America and Southern Brazil.[1] 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.[2][3] Their nests are disc-shaped and hang from the undersides of leaves and tree branches.[2] This particular species of wasp can be hard to study because they frequently abandon their nests.[4]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.[5]
