Polistes
Wasps of the cosmopolitan genus ''Polistes'' (the only genus in the tribe Polistini) are the most familiar of the polistine wasps, and are the most common type of paper wasp in North America. Walter Ebeling coined the vernacular name "umbrella wasps" for this genus in 1975 to distinguish it from other types of paper wasp, in reference to the form of their nests. It is also the single largest genus within the family Vespidae, with over 300 recognized species and subspecies. 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. The European paper wasp, ''Polistes dominula'', was introduced into the US about 1981 and has quickly spread throughout most of the country, in most cases ...

Polistes Dominula
The European paper wasp (''Polistes dominula'') is one of the most common and well-known species of social wasps in the genus ''Polistes''. Its diet is more diverse than those of most ''Polistes'' species—many genera of insects versus mainly caterpillars in other ''Polistes''—giving it superior survivability compared to other wasp species during a shortage of resources. The dominant females are the principal egg layers, while the subordinate females ("auxiliaries") or workers primarily forage and do not lay eggs. This hierarchy is not permanent, though; when the queen is removed from the nest, the second-most dominant female takes over the role of the previous queen. Dominance in females is determined by the severity of the scatteredness in the coloration of the Clypeus (arthropod anatomy), clypeus (face), whereas dominance in males is shown by the variation of spots of their abdomens. ''P. dominula'' is common and cosmopolitan due to their exceptional survival features such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polistes Metricus
''Polistes metricus'' (metric paper wasp or metricus paper wasp) is a wasp native to North America. In the United States, it ranges throughout the southern Midwest, the South, and as far northeast as New York, but has recently been spotted in southwest Ontario. A single female specimen has also been reported from Dryden, Maine. ''Polistes metricus'' is dark colored, with yellow tarsi and black tibia. Nests of'' Polistes metricus'' can be found attached to the sides of buildings, trees, and shrubbery. Like other ''Polistes ''species, ''P. metricus'', has evolved eusociality and demonstrates behaviors including nestmate discrimination and local mate competition. Like the other members of the order Hymenoptera, ''Polistes metricus'' has a haplodiploid genetic system. Nests of ''P. metricus'' have distinct characteristics like the ability to share nests with other ''Polistes'' species and reuse nests multiple seasons. Another distinction is that ''Polistes metricus'' foragers take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polistes Gallicus
''Polistes gallicus'' is a species of paper wasp found in various parts of Europe, excluding England, Denmark, and Scandinavia, from warmer climates to cooler regions north of the Alps. Nests of these social insects are created in these various conditions. The ''Polistes'' species use an oral secretion to construct their nests, which consist of a combination of saliva and chewed plant fibers. This structural mixture physically protects the nest from various harsh elements and from weathering over time. Description and identification ''P. gallicus'', like other members of the subgenus ''Polistes (Polistes)'', has recognizable, bright yellow and black markings. They have smaller bodies than many of its allies that overlap in range, and their bodies are largely hairless. The species may be separated from allies through the following traits. Females are identified by having 12 antennal segments and 6 abdominal segments. The antennae are orange and paler on the ventral surface than i ...

Polistes Semenowi
''Polistes semenowi'' is a species of paper wasp in the genus ''Polistes ''that is found in southeastern and southern central Europe, as well as central Asia, and was until 2017 erroneously known by the name ''Polistes sulcifer'', while a different species was incorrectly believed to represent ''P. semenowi'' (this species has been named '' Polistes austroccidentalis''). It is one of only four known ''Polistes'' obligate social parasites, sometimes referred to as " cuckoo paper wasps", and its host is the congeneric species ''Polistes dominula''. As an obligate social parasite, this species has lost the ability to build nests, and relies on the host workers to raise its brood. ''P. semenowi'' females use brute force, followed by chemical mimicry in order to successfully usurp a host nest and take over as the queen. Taxonomy and phylogeny ''Polistes'' is the only genus in the tribe Polistini of the subfamily Polistinae. Species in this subfamily are one of several lineages often ...

Polistes Versicolor
''Polistes versicolor'', also known as the variegated paper wasp or yellow paper wasp, is a subtropical social wasp within ''Polistes'', the most common genus of paper wasp. It is the most widely distributed of South American wasp species and is particularly common in the Southeastern Brazilian states.Zara, Fernando, and Jose Balestieri. "Behavioural Catalogue of ''Polistes versicolor'' Olivier (Vespidae: Polistinae) Post-emergent Colonies." ''Naturalia'' 25 (2000): 301-19. Print. This social wasp is commonly referred to as the yellow paper wasp due to the distinct yellow bands found on its thorax and abdomen.Gobbi, Nivar, Fernando B. Noll, and Marcelo A. H. Penna. "‘Winter’ Aggregations, Colony Cycle, and Seasonal Phenotypic Change in the Paper Wasp ''Polistes versicolor'' in Subtropical Brazil." ''Naturwissenschaften'' 93.10 (2006): 487-94. Web. The ''P. versicolor'' nest, made of chewed vegetable fiber, is typically a single, uncovered comb attached to the substratum by a s ...

Polistinae
The Polistinae is a subfamily of eusocial wasps belonging to the Family (biology), family Vespidae. They are closely related to the more familiar wasps (“yellowjackets” as they are called in North America) and true hornets of the subfamily Vespinae, containing four tribes. With about 1,100 species total, it is the second-most diverse subfamily within the Vespidae, and while most species are tropical or subtropical, they include some of the most frequently encountered large wasps in temperate regions. The Polistinae are also known as paper wasps, which is a misleading term, since other wasps (including the wasps in the subfamily Vespinae) also build nests out of paper, and because some epiponine wasps (e.g., ''Polybia emaciata'') build theirs out of mud, nonetheless, the name "paper wasp" seems to apply mostly, but not exclusively, to the Polistinae, especially the Polistini. Many polistines, such as ''Polistes fuscatus,'' ''Polistes annularis'', and ''Polistes exclamans'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Wasp
Paper wasps are Vespidae, vespid wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct nests made of gray or brown papery material. Some types of paper wasps are also sometimes called umbrella wasps, due to the distinctive design of their nests."Paper Wasp" Microsoft Encarta Online Encyclopedia 2006. Species The name "paper wasps" typically refers to members of the Vespidae, vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae (hornets and yellowjackets) and Stenogastrinae, which also make nests out of paper. Twenty-two species of ''Polistes'' paper wasps have been identified in North America and approximately 300 species have been identified worldwide. The most common ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as ''Polistes fuscatus'', ''Vespa orientalis'', and ''Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species.

Cuticular Hydrocarbon
Insects (from Latin ') are pancrustacean 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 one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Jacket
Yellowjacket or yellowjacket is the common name in North America for predatory social wasps of the genera ''Vespula'' and ''Dolichovespula''. Members of these genera are known simply as "wasps" in other English-speaking countries. Most of these are black and yellow like the eastern yellowjacket ''Vespula maculifrons'' and the aerial yellowjacket ''Dolichovespula arenaria''; some are black and white like the bald-faced hornet, ''Dolichovespula maculata''. Others may have the abdomen background color red instead of black. They can be identified by their distinctive markings, their occurrence only in colonies, and a characteristic, rapid, side-to-side flight pattern prior to landing. All females are capable of stinging. Yellowjackets are important predators of pest insects. Identification Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as ''Polistes dominula''. A typical yellowjacket worker is about long, with alternating bands on the abdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyne
The gyne (, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens, whereas female workers are typically barren and cannot become queens. Having a queen is what makes a "queenright" hive, nest, or colony of eusocial insects. A colony with multiple queens is said to be a polygyne form, whereas one with only one is a monogyne form. The red imported fire ant is known to have colonies in both polygyne and monogyne forms. The small red ant, ''Leptothorax acervorum'', has colonies that switch from monogyny to polygyny as a result of seasonal fluctuations. The little fire ant ''Wasmannia auropunctata'' produces unique kinds of meiotic oocytes with a drastic reduction in recombination. These oocytes may either fuse together for gyne production ( automictic parthenogenesis with central fusion) or be fertilized by male gametes for the ...
