Melittobia Australica
''Melittobia australica'' is a species of chalcid wasp from the family Eulophidae which is a gregarious ecto-parasitoid of acuealate Hymenoptera. Description ''Melittobia australica'' is a small wasp between 1.1 and 1.4 mm in length but has the typical wasp body plan of a head, thorax, abdomen body structure with the "wasp waist". It is sexually dimorphic with males is normally being larger than females, males are 1.2 to 1.4 mm in length while females are 1.1 to 1.3 mm. Males also have a with a wider head and smaller wings are smaller and their antennal scape is significantly broader. The colour difference is that the males are also a honey brown whereas the females are coloured dark brown. There are at least two morphs of females in ''M. australica'' which differ in the size of the abdomen, the size of the eyes and the extent of wing development. The "crawler" morph have a normal abdomen, small eyes and underdeveloped wings. The "flier" and possibly the "jumper" ...

Melittobia Acasta
''Melittobia'' is a genus of hymenopteran insects of the family Eulophidae. Biology ''Melittobia'' wasps are gregarious ectoparasitoids on solitary bees, honeybee and wasps, and also of any insect cohabitants of their hosts' nests, such as Coleoptera, Lepidoptera and Diptera. One species has been reared from puparia of ''Anastrepha'' fruit flies collected from fallen fruits in Mexico. They show intrasexual and intersexual dimorphism, with the males being blind and flightless and two castes of females, one long winged and one short winged, which are probably determined by nutrition. The females exhibit primitive social traits while the males are competitive, ferociously fighting and killing their male siblings. The males attract the females using a pheromone and they have an elaborate courtship ritual. They have a skewed sex ratio with 95% of the offspring being females which are from fertilised eggs but males are produced asexually through arrhenotoky. The females have overlapp ...

Pison
''Pison'' is a cosmopolitan genus of wasps within the family Crabronidae. The genus comprises 145 described species, although many species, especially in South America remain undescribed.Bohart, Richard Mitchell, and Arnold S. Menke. Sphecid wasps of the world: a generic revision. University of California Press, 1976. Distribution The genus is found throughout the tropical and warm temperate regions of the world, but does not extend into the more northerly temperate regions. Most species occur in the Southern Hemisphere, with a third of species occurring in Australia. This distribution pattern has been thought to indicate that the genus was once much larger, and has declined in the face of competition with more competitive wasp genera, leaving the genus largely concentrated in geographically-isolated regions.Turner, Rowland E. "29. Notes On The Wasps Of The Genus Pison, And Some Allied Genera." Proceedings of the Zoological Society of London. Vol. 86. No. 4. Blackwell Publishin ...

Honeybees
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the western honey ...

Bombus
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

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 ...

Vespula
''Vespula'' is a small genus of social wasps, widely distributed in the Northern Hemisphere. Along with members of their sister genus ''Dolichovespula'', they are collectively known by the common name yellowjackets (or yellow jackets) in North America. ''Vespula'' species have a shorter oculomalar space (shown in the figure below right) and a more pronounced tendency to nest underground than ''Dolichovespula''. Notable species * While most species of this genus inhabit North America, four ''Vespula'' species inhabit Europe, namely ''V. austriaca, V. germanica, V. rufa'' and ''V. vulgaris'' * Two common European species, the German wasp (''Vespula germanica'') and the common wasp (''Vespula vulgaris''), have established in other countries: both species are now found in New Zealand, Australia and South America, while the former has also been introduced in North America, and the latter in southern Africa. * The eastern yellowjacket (''Vespula maculifrons'') and western yellowjacket ...

Social Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can Stinger, sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are Eusociality, eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex-determination system, sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently ...

Mud Dauber
Mud dauber (or "mud wasp" or "dirt dauber") is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae which build their nests from mud; this excludes members of the family Vespidae (especially the subfamily Eumeninae), that are instead referred to as "potter wasps". Mud daubers belong to different families and are variable in appearance. Most are long, slender wasps about in length. The name refers to the nests that are made by the female wasps, which consist of mud molded into place by the wasp's mandibles. Mud daubers are not normally aggressive, but can become belligerent when threatened. Stings are uncommon. Nests The organ pipe mud dauber, one of many mud daubers in the family Crabronidae, builds nests in the shape of a cylindrical tube resembling an organ pipe or pan flute. Common sites include vertical or horizontal faces of walls, cliffs, bridges, overhangs and shelter caves or other structures. The nest of a black and yellow mud ...

Megachile
The genus ''Megachile'' is a cosmopolitan group of solitary bees, often called leafcutter bees or leafcutting bees; it also includes the called resin bees and mortar bees. While other genera within the family Megachilidae may chew leaves or petals into fragments to build their nests, certain species within ''Megachile'' neatly cut pieces of leaves or petals, hence their common name. This is one of the largest genera of bees, with more than 1500 species in over 50 subgenera. The alfalfa leafcutter bee (''Megachile rotundata'') is managed on a commercial scale for crop pollination, and has been introduced by humans to various regions around the world. Ecology Nests are sometimes constructed within hollow twigs or other similarly constricted natural cavities, but often are in burrows in the ground. Nests are typically composed of single long columns of cells, the cells being sequentially constructed from the deepest portion of the tunnel outwards. The female places an egg in ...

Sceliphron
''Sceliphron'', also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud. Nests are frequently constructed in shaded niches, often just inside of windows or vent openings, and it may take a female only a day to construct a cell requiring dozens of trips carrying mud. Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. Females of some species lay a modest average of 15 eggs over their whole lifespan. Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging. As is the case with many insect genera, there are many ...

Mites
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of arachnids ...
