Apoica is a genus of eusocial paper wasp found throughout the Central and South American tropics. These wasps are truly nocturnal, carrying out their foraging activities after the setting of the sun. They prefer to construct their nests, which have an open comb like many paper wasps, under large leaves, or in shrubs. During the day, wasps covering the comb fan their wings to cool the nest, keeping it at a suitable temperature for larval development.
The Central American paper wasp is a nocturnal eusocial wasp. It is famous for its swarm based emigration behavior, and is native to the lowlands of Central and northern South America. This species has developed special night vision adaptations to facilitate their night-time swarming and foraging behavior and has important medicinal properties for the Pankararú people of Brazil.
Brachygastra lecheguana, formerly known as Nectarina lecheguana, is a species of dark paper wasp found across North and South America. It nests in underbrush in grassland-type environments, and produces honey, characteristic of the genus Brachygastra.
Agelaia vicina is a species of wasp in the genus Agelaia. They are neotropical social wasps known to have the largest colony sizes and nest sizes among social wasps, with some colonies exceeding over one million individuals. They are predators of land arthropods, consuming both insects and spiders alike. Recent sperm morphology studies have shown that although Vespidae belong to the superfamily Vespoidea, A. vicina may be more phylogenetically related to Apoidea.
Synoeca cyanea, commonly known as the marimbondo-tatu in Brazil, is a swarm-founding eusocial wasp. Native to Brazil and Argentina, S. cyanea is one of the largest and most aggressive species of social wasps and is feared in many rural areas. It begins its colony cycle in the early spring and continues until nest abandonment. Throughout its life, S. cyanea forage sugary substances and animal carcasses for food and wood pulp for its nest. S. cyanea is also known for its strong venom, which is enough to cause haemolytic activity.
Angiopolybia pallens is a species of social wasp predominantly found in South America. The wasp is generally seen in Brazilian rainforests. This species was discovered by Lepeletier in 1836. It typically feeds on nectar and carrion. In fact much of its feeding behavior and impact on humans is centered on feeding on animal carcasses. The wasp species displays a caste differentiation that can be seen by difference in ovarian development. Additionally they have a unique colony establishment procedure. It begins with a few individuals from the nest leaving to find a good site and then the rest of the colony follows using specific communication signals that are further discussed in this article.
Agelaia pallipes is a species of social paper wasp found from Costa Rica to Brazil, Argentina and Paraguay. A. pallipes is ground-nesting and is one of the most aggressive wasps in South America. This species is a predator of other insects, including flies, moths, and ground crickets, as well as baby birds.
Protonectarina sylveirae, commonly referred to as the Brazilian wasp, is a neotropical swarm-founding wasp species that ranges widely across South America. This species relies heavily on the consumption of animal protein rather than nectar. P. sylveirae preys heavily on agricultural pests to coffee crops, keeping pest populations low.
Leipomeles dorsata is a neotropical paper wasp that is found across Central America and northern South America. It is a eusocial wasp with little differentiation between reproducing and non-reproducing females. In fact, workers can become temporary reproductives if the main reproductives are killed, allowing reproduction to continue until the main reproductive population recovers. The colony cycles through different ratios of main reproductive females and subordinate reproductive females, starting with few or no primary reproducing females, and increasing until there are only main reproductives.
The African swarm-founding wasp, Polybioides tabidus, is a social paper wasp from the order Hymenoptera that is typically found in Central Africa. This wasp is unique in that it exhibits cyclical oligogyny, meaning queen number varies with colony cycle. After several generations of production of workers and future queens, a subset of many workers and queens leave the original colony to begin a new one. The new colony does not produce new queens until current queens from the old colony have died. P. tabidus has been observed to display both predator and scavenger behavior, depending on the food sources available.
Protopolybia exigua is a species of vespid wasp found in South America and Southern Brazil. 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. 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. 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.
Polybia sericea is a social, tropical wasp of the family Vespidae that can be found in South America. It founds its colonies by swarming migrations, and feeds on nectar and arthropods.
Ropalidia romandi, also known as the yellow brown paper wasp or the yellow paper wasp. is a species of paper wasp found in Northern and Eastern Australia. R. romandi is a swarm-founding wasp, and manages perennial nests. Its nests are known as 'paper bag nests' and have different architectural structures, depending on the substrates from which they are built. The specific name honors Gustave, baron de Romand, a prominent French political figure and amateur entomologist.
Synoeca surinama is a Neotropical swarm-founding wasp of the tribe Epiponini. It is known for its metallic blue and black appearance and painful sting. S. surinama builds nests on tree trunks and can be found in tropical climates of South America. When preparing to swarm, there are a number of pre-swarming behaviors that members of S. surinama colonies partake in, such as buzzing runs and occasional brood cannibalism. In S. surinama, social environmental conditions determine the caste ranks of individuals in the developing brood. Unlike less primitive Hymenoptera species, S. surinama display little morphological variation between egg laying queens and workers. S. surinama wasps visit flowering plants and are considered pollinators. When these wasps sting, the stinger is left in the victim and the wasp ultimately dies.
Parachartergus fraternus is a neotropical, swarm founding, polistine wasp species that is distributed throughout Central and South America. They live in nests in second growth tropical dry forests, near pasture fields, roadside areas, and urban areas as well. These wasps eat insects, such as caterpillars of Lepidoptera. They also drink nectar, honeydew, and water. The workers capture their prey during foraging. They also use venom to paralyze their prey in order to consume it later. P. fraternus wasps are not very aggressive and they do not attack when the nest is approached.
Synoeca septentrionalis is one of five species of wasps in the genus Synoeca. It is a swarm-founding wasp that is also eusocial, exhibiting complicated nest structure and defense mechanisms and a colony cycle including a pre-emergence phase and a post-emergence phase. It is typically found in areas from Central to South America. This wasp is one of the larger species of paper wasps and exhibits multiple morphological adaptations as a result of this. Synoeca septentrionalis is known for possessing a very painful sting.
Agelaia multipicta is a swarm-founding, highly eusocial wasp that lives in Mexico, Argentina, Trinidad and southern Brazil. It nests in natural cavities such as hollow trees and aggressively defends the nest from ants, who are brood predators. The workers and queens are morphologically distinguished by ovarian development as well as external features such as a larger petiole and gaster in the queen. Like other carrion-eating (necrophagous) wasp species, A. multipicta plays a scavenging role in the ecosystem. Agelaia multipicta was described by the Irish entomologist Alexander Henry Haliday in 1836.
Brachygastra scutellaris, a honey wasp, is a Neotropical, swarm-founding species that is found in South America and has a medium-sized population of 100-1000 individuals per colony. It stores large amounts of nectar in its nest for the production of honey, and it was even found that at certain times of the year, the nectar is toxic to humans, as they will extract nectar from hallucinogenic plants, depending on the season.
Polybia paulista is a species of eusocial wasp occurring in Brazil, Paraguay, and Argentina.
Parachartergus is a genus of epiponine social wasps belonging to the subfamily Polistinae. Species include:
