Nest Usurpation
Nest usurpation is when the queen of one species of eusocial insects takes over the colony of another species. Cuckoo bumblebees (''Psithyrus'') and cuckoo paper wasps (''Polistes'') are known for usurpation. Nest usurpation most frequently occurs during the late pre-emergence stage of a nest. A foundress is a member of one species, usually female that finds a nest in the late pre-emergence stage and takes control of the colony of that nest. The usurper or queen is a member of one species, usually female that gives raise to and controls the colony of a particular nest. Usurpation can include killing the true queen, after which the usurper queen lays eggs then exploits the host workers (thus, no workers exist within the usurper species) to feed her and her developing young (brood parasitism Brood parasitism is a subclass of parasitism and phenomenon and behavioural pattern of animals that rely on others to raise their young. The strategy appears among birds, insects and fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eusocial
Eusociality ( Greek 'good' and social) is the highest level of organization of sociality. It is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society, sometimes called castes. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform behaviors characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality has evolved among the insects, crustaceans, trematoda and mammals. It is most widespread in the Hymenoptera (ants, bees, and wasps) and in Isoptera (termites). A colony has caste differences: queens and reproductive males take the roles of the sole reproducers, while soldiers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psithyrus
Cuckoo bumblebees are members of the subgenus ''Psithyrus'' in the bumblebee genus '' Bombus''. Until the 1990s, ''Psithyrus'' was considered to constitute a separate genus.Williams, P.H. 1994. Phylogenetic relationships among bumblebees (''Bombus'' Latr.): A reappraisal of morphological evidence. Systematic Entomology 19: 327-344. They are a specialized socially parasitic lineage which parasitises the nests of 'true' bumblebees; they do not collect pollen or establish their own nests. Cuckoo bumblebees do not create a worker caste and produce only male and female reproductives. They are considered inquilines in the colonies of 'true' bumblebees. Cuckoo bumblebee females emerge from hibernation later than their host species to ensure that their host has had sufficient time to establish a nest. Before finding and invading a host colony, a ''Psithyrus'' female feeds directly from flowers until her ovaries are sufficiently developed, at which time she begins seeking a nest to inva ...

Cuckoo Paper Wasp
The name cuckoo paper wasp refers to a monophyletic species group of brood-parasitic paper wasps in the genus ''Polistes''. This species group contains only four species; '' Polistes atrimandibularis'', '' P. austroccidentalis'', '' P. maroccanus'', and '' P. semenowi'',Schmid-Egger C, van Achterberg K, Neumeyer R, Morinière J, Schmidt S (2017) Revision of the West Palaearctic ''Polistes'' Latreille, with the descriptions of two species – an integrative approach using morphology and DNA barcodes (Hymenoptera, Vespidae).

Polistes
''Polistes'' is a cosmopolitan genus of paper wasps and the only genus in the tribe Polistini. Vernacular names for the genus include umbrella wasps, coined by Walter Ebeling in 1975 to distinguish it from other types of paper wasp, in reference to the form of their nests, and umbrella paper wasps. ''Polistes'' is the single largest genus within the family Vespidae, with over 200 recognized species. Their innate preferences for nest-building sites leads them to commonly build nests on human habitation, where they can be very unwelcome; although generally not aggressive, they can be provoked into defending their nests. All species are predatory, and they may consume large numbers of caterpillars, in which respect they are generally considered beneficial. Description As part of subfamily Polistinae, ''Polistes'' wasps are covered in short and inconspicuous hair, have a clypeus with a pointed apex, have a gena that is wide throughout, tergum 1 of the metasoma is almost straig ...

Metapolybia Cingulata
''Metapolybia cingulata'' (Fabricius, 1804) is a species of social paper wasp known for having queens who exhibit usurpation behaviors and also for having flexible behavior groups. It is difficult to tell what a specific wasp's role is just upon observation. Therefore, dissections are usually performed in order to determine the sex, and thus the wasp's role in the colony. The regulating behavior, or nest building, most closely resembles that of primitive ''Polistes'' models where a queen solicits liquid from a fellow worker and then takes pulp to initiate building a cell without leaving the nest. In nest building, the amount of water present in the nest as well as the activity of the builders of the nests determines the activity of the colony. Taxonomy ''Metapolybia cingulata'' is a member of the family Vespidae of eusocial wasps within the order Hymenoptera. Subfamily Polistinae is known commonly as " paper wasps". Genus ''Metapolybia'' contains 11 species, of which '' M. aztecoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Behavior
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...
