Tachytes Aestuans
''Tachytes'' is a genus of predatory, solitary wasps, containing about 300 species. Etymology The name of the genus derives from the Greek ταχύτης (''tachytes''), meaning swiftness or speed. Distribution These wasps have a worldwide distribution throughout temperate and tropical regions. Description Adults are typically black, with light or clear wings, and sometimes a red or brown gaster or legs. They are about 12 mm long, but can range from 4 mm to 24 mm. Many species have green eyes, which is distinctive of the genus. They often possess short golden hairs and a round build, which can give them a bee-like appearance. Biology ''Tachytes'' generally predates on Orthoptera (grasshoppers and katydids, especially those of the families Acrididae, Tettigoniidae, Tetrigidae, and Tridactylidae), though ''Tachytes bidens'' reportedly predates on geometer moths. Like other hunting wasps, the female captures a prey item, stings to paralyze it, and seals it in a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachytes Etruscus
''Tachytes etruscus'' is a predatory, solitary wasp belonging to the family Crabronidae. The species was first described by Pietro Rossi in 1790. Distribution This species is present in Albania, Austria, Bulgaria, France, Greece, Hungary, Italy, Portugal, Russia, Slovenia and Spain. Description ''Tachytes etruscus'' can reach a length of in the female, and of in males. Its body is largely black, with silver stripes on the abdomen and brown to ferruginous wings, legs, mandibles and palpi. Biology Females of this species usually predate on grasshoppers. The females dig holes in the ground in which they build some cells. Then they capture a prey grasshopper, paralyze it with a sting, carry it inside the underground nest and seal it in the burrow along with an egg. The larva consumes the prey during development. Males apparently guard the entrance of the burrows with developing females, waiting for them to emerge. These wasps have a preference for flowers of ''Solidago virgaurea ...

Orthoptera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera).

Hill-topping (biology)
Hill-topping (more often spelt hilltopping) is a mate-location behaviour seen in many insects including butterflies, dragonflies, bumblebees, wasps, beetles and flies. Males of many butterfly species may be found flying up to and staying on a hilltop - for days on end if necessary. Females, desirous of mating, fly up the hill. Males dash around the top, competing for the best part of the area - usually the very top; as the male with the best territory at the top of the hill would have the best chance of mating with the occasional female, who knows the "top male" must be strong and thus genetically fit. Many authors consider this as a form of lekking behaviour. Many butterfly species including swallowtails, nymphalids, metal-marks and lycaenids are known to hill-top. In some ''Acraea'' butterflies, widespread infection by ''Wolbachia ''Wolbachia'' is a genus of intracellular bacteria that infects mainly arthropod species, including a high proportion of insects, and also s ...

Sphex
Wasps of the genus ''Sphex'' (commonly known as digger wasps) are cosmopolitan predators that sting and paralyze prey insects. ''Sphex'' is one of many genera in the old digger wasp family Sphecidae ('' sensu lato''), though most apart from the Sphecinae have now been moved to the family Crabronidae. There are over 130 known ''Sphex'' species. Behaviour In preparation for egg laying, they construct a protected "nest" (some species dig nests in the ground, while others use pre-existing holes) and then stock it with captured insects. Typically, the prey are left alive, but paralyzed by wasp toxins. The wasps lay their eggs in the provisioned nest and the wasp larvae feed on the paralyzed insects as they develop. The great golden digger wasp ('' Sphex ichneumoneus'') is found in North America. The developing wasps spend the winter in their nest. When the new generation of adults emerge, they contain the genetically programmed behaviors required to carry out another season of nes ...

Jean-Henri Fabre
Jean-Henri Casimir Fabre (21 December 1823 – 11 October 1915) was a French naturalist, entomologist, and author known for the lively style of his popular books on the lives of insects. Biography Fabre was born on 21 December 1823 in Saint-Léons in Aveyron, France. Fabre was largely an autodidact, owing to the poverty of his family. Nevertheless, he acquired a primary teaching certificate at the young age of 19 and began teaching in Carpentras whilst pursuing further studies. In 1849, he was appointed to a teaching post in Ajaccio (Corsica), then in 1853 moved on to the lycée in Avignon. Fabre was a popular teacher, physicist, chemist and botanist. However, he is probably best known for his findings in the field of entomology, the study of insects, and is considered by many to be the father of modern entomology. Much of his enduring popularity is due to his marvellous teaching ability and his manner of writing about the lives of insects in biographical form, which he pref ...

Hunting Wasp
Hunting wasps are members of various taxa of the insect order Hymenoptera. Their habits and affinities vary in many ways, but all practise parental care of their larvae in that they capture prey, usually insects, to feed their larvae. Whether solitary or social, most species construct some form of protection or nest in which they hide the prey and in which the larvae can feed and pupate in reasonable security. Most solitary hunting wasps sting their prey in such a manner as to paralyse it without killing it. As a result it remains fresh for the young to eat. In contrast carnivorous social wasps generally feed prey piecemeal to the larvae as soon as they bring it back to the colony, so there is no need for preservation of the material. A minority of solitary hunting wasps, such as certain Bembicinae, also butcher their prey before feeding it to the larvae. Overview ''Hunting wasp'' is not a biological taxon, but rather describes certain ecological strategies that occur within ...

Geometer Moth
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek ''geo'' γεω (derivative form of or "the earth"), and ''metron'' "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, ''Biston betularia'', which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests. Adults Many geometrids have slender abdomens and broad wings which are usually held flat with the hindwings visible. As such, they appear rather butterfly-like, but in most respects they are typical moths; the majority fly at night, they possess a frenulum to link the wings, and the ...

Tridactylidae
The Tridactylidae are a family in the insect order Orthoptera. They are small, mole-cricket-like insects, almost always less than long when mature. Generally they are shiny, dark or black, sometimes variegated or sandy-coloured. They commonly live in short tunnels and are commonly known as pygmy mole crickets, though they are not closely related to the true "mole crickets" (Ensifera), as they are included in the Caelifera suborder (related to grasshoppers). Description The Tridactylidae are small members of the Orthoptera, most species being less than 10 mm in length, though some approach 20 mm. They have a wide, but patchy, distribution on all continents but Antarctica. Being so small and inconspicuously coloured, while living in shallow burrows in moist sandy soil, they are not generally familiar to non-entomologists. They have several unusual features, for example, the posterior femora are greatly enlarged, being strongly adapted for leaping; in some species tho ...
