Leipomeles dorsata is a neotropical paper wasp that is found across Central America and northern South America. [1] It is a eusocial wasp with little differentiation between reproducing and non-reproducing females. [1] In fact, workers can become temporary reproductives if the main reproductives are killed, allowing reproduction to continue until the main reproductive population recovers. [1] 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. [1]

Contents

Taxonomy and phylogeny

Leipomeles dorsata is part of the tribe Epiponini, a group of neotropical eusocial wasps. [1] This species has a complex taxonomic history. Other species have been synonymized into this species, the first being by Fabricus in 1804. [2] The initial classification of the species Polybia nana became Leipomeles nana in 1912 and was eventually synonymized with L. dorsata. [2] L. nana was the junior synonym and L. dorsata is the senior synonym. [2] However, L. nana has since been reclassified as its own distinct species, Leipomeles spilogastra, and is no longer a synonym of L. dorsata. [2]

Description and identification

Leipomeles dorsata females are a variety of colors, varying between chestnut to dark brown. Shade generally varies with age, with individuals becoming darker in color as they get older. However, egg-laying females sometimes exhibit yellow patterns on the head and thorax. [1] The abdomens of this species are generally an elongated diamond-like shape and the wings have a flattened semi-circular shape. [3]

Nest Identification

A piece of L. dorsata nest

Leipomeles dorsata nests are made of extremely thin material classified as paper. [4] These nests may or may not have a petiole. [3] If there is a petiole present it is covered in a sticky substance that protects the nest against ants, which are brood predators. [4] The nests are a series of combs underneath the leaf, and may be fused. [4] Generally, this species applies colored pulp to the outside of the nest, thought to be a method of camouflage. [3]

Distribution and habitat

Leipomeles dorsata is a neotropical species present in the rainforests of Central and South America. They build their nests on the underside of large tree leaves, making them extremely adapted to a niche of the rainforest habitat. [1] It is mainly found in the lowland areas of these forests from 50 to 500m elevations. [5] Large scale morphological studies rely mostly on collections from Costa Rica. [1]

Colony cycle

This species has a distinct colony cycle, with primary egglayers only being part of the colony for a limited amount of time. [1] Reproductives of L. dorsata consist of primary yellow egg layers and subordinate brown egg layers. [1] The yellow females have longer ovaries than the brown females. [1] This is likely due to the brown egglayers being former worker wasps that have become egg layers in the colony. [1] All of the yellow egg layers are older females, but there is usually a mix between ages in the brown egg layers. [1] This occurs when a colony is deprived of its yellow egg layers, the brown workers are signaled to become replacements, [1] an example of cyclical oligogyny. [6] Eventually, the older yellow egg layer population recovers and the workers aggressively prevent other females from becoming egg layers. [7]

Behavior

Reproductive suppression

When the population of primary egg layers is robust, workers aggressively suppress reproduction by other workers. This aggression is exhibited between nest mates, through denying food and physically biting rivals. [6] Older mature primary egglayers will suppress reproduction in the younger brown egglayer population. However, if the colony begins losing its primary reproductives then it is advantageous for the colony if the subordinate (brown) egg layers reproduce, and they will do so since they are no longer suppressed by the yellow egglayers. [1]

Communication

Leipomeles dorsata display trail marking during colony migration, which is rather common for neotropical swarming wasps. [8] The scouts will drag or rub the underside of their bodies on surfaces, such as leaves along the migration route. [8] However, what makes L. dorsata unique is that it lacks the Richard's Organ, which is generally associated with pheromone production in other species that exhibit this behavior. [8]

Mating behavior

As is the case of most Epiponini wasps, the reproductives stay in the nest, which requires males to find their way into the nest to mate. [9] An explanation for the male's ability to find potential mates is that they patrol for mates and follow colony migration pheromones that were laid down by scouts to new nest sites. [9] In fact, males have been sighted at L. dorsata colonies as soon as the first day of nest construction. [8] In addition, males then might also be attracted by reproductives' own pheromones inside of the nest, and use those to find their way into the nest to mate. [9]

Kin selection

Worker queen conflict

Leipomeles dorsata is a species that does not have queens per se, but rather multiple egg layers that are in charge of reproduction. [1] The degree that these egg layers are specialized for reproduction depends on how functional their ovaries are. There are four patterns of ovaries that were observed in this species: no oocytes, immature oocytes, well-developed oocytes with at least one mature oocyte, and several well-developed and completely mature oocytes. [1] The females with the more mature reproductive organs are the ones that have greater reproductive success because they are more specialized; in cases where there are both brown worker egg-layers with the third reproductive pattern and yellow reproductives with the fourth reproductive pattern, the yellow females out perform and outcompete the brown ones. [1] However, if there are no yellow females present than the brown workers may be solely responsible for the colony's reproduction.

Life history

Colony survivorship

Leipomeles dorsata has several qualities that allow for high colony survivorship. The main quality is that they display cyclical oligogyny. [1] This allows workers to temporarily take the place of egg layers when there are few or no egglayers, allowing the population to survive during a period of high egglayer mortality. [1] Also the ability of male Epiponini to find nests with virgin females contributes to colony survivorship. [9] This ensures that copulation can take place in colonies where there has been loss of reproductives which guarantees the reproductive success of the colony. [9]

Camouflage

Leipomeles dorsata builds its nests in a way that disguises it from vertebrae predators. [10] They choose an overhanging leaf and build the nest underneath it so that it is hidden, and then proceed to construct an envelope that mimics the color and patterns of the leaves surrounding the nest. [10] This mimicry results from the addition of colored leave pulp. Wasps chew up leaves on the surrounding tree, and then applied the resulting mixture to the outside of the nest. [3]

Interaction with other species

Predators and predation

Leipomeles dorsata, as with other paper wasps mainly feed on insects and other arthropods that they find by foraging. [5] The main predators of L. dorsata, as with other neotropical paper wasps, are ants and birds that feed on a variety of insects. [5] Specifically, army ants present a grave threat to paper wasps in the tropics, and nests and behaviors have evolved as a way to combat this predation pressure; in the case of L. dorsata, this is seen in the chemical defense described below. [5]

Defense

In the case of L. dorsata, defense is passive rather than active. Nest petioles are covered in a sticky substance that protects the nest and the larva inside from ants. [4] This protection is perhaps the reason that this species has extremely docile females. [1] In many species that employ this method, the small size of the wasps requires alternate defense systems rather than aggression. Other examples include chemical defense and large numbers of adults at the foundational stage. [11]

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.

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.

<i>Ropalidia romandi</i> Species of wasp

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.

<i>Synoeca surinama</i> Species of wasp

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.

<i>Synoeca septentrionalis</i> Species of stinging wasp

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.

<i>Polistes dorsalis</i> Species of wasp

Polistes dorsalis is a species of social wasps that can be found throughout various parts of North America. It is classified under the Vespidae within the genus of Polistes. Male Polistes dorsalis wasps can be distinguished from other Polistes species by their distinctly prominent median tubercle of sternum 7. Both sexes can also be recognized due to their v- shaped yellow markings on their head. They are distributed widely across North America and can be found in sheltered nests, typically closer to the ground. These wasps live in a dominance hierarchy in which the queen's role differs from that of ordinary workers. When threatened, these wasps can deliver moderately painful stings. Their venom might also be of human interest for their antimicrobial uses.

<i>Agelaia multipicta</i> Species of wasp

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.
