Gasteruption jaculator is a species of insect in the family Gasteruptiidae.
This species is mainly present in Austria, Belgium, Great Britain, Czech Republic, Finland, France, Germany, Greece, Hungary, Italy, Poland, Romania, Russia, Slovakia, Spain, Sweden, Switzerland, in the eastern Palearctic realm, and in the Near East. [1]
The head and thorax are completely black. The head is strongly rounded, the thorax is elongated in a sort of long neck ( propleura ), which separates the head from the body. Also the abdomen is strongly stretched, broader at the posterior end and placed on the upper chest ( propodeum ). The colour of the abdomen is black, with reddish-orange rings. The tibiae of the hind legs are club shaped. In the female the ovipositor is usually very long with a white tip. In resting position, these wasps slowly and rhythmically raise and lower the abdomen.
The female of this parasitic wasp lays its eggs on the body of larvae of solitary bees or wasps using its long ovipositor. Upon hatching, its larvae will devour grubs and its victim's supplies of pollen and nectar. The adults grow up to 10–17 millimetres (0.39–0.67 in) long and can mostly be encountered from May through September feeding on Apiaceae species.
Gasteruption jaculator has been found visiting various flowers, or hovering around the nests of solitary bees and wasps in gardens and meadows. The species is commonly found during May to September.
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
Apocrita is a suborder of insects in the order Hymenoptera. It includes wasps, bees, and ants, and consists of many families. It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" (petiole) formed between the first two segments of the actual abdomen; the first abdominal segment is fused to the thorax, and is called the propodeum. Therefore, it is general practice, when discussing the body of an apocritan in a technical sense, to refer to the mesosoma and metasoma rather than the "thorax" and "abdomen", respectively. The evolution of a constricted waist was an important adaption for the parasitoid lifestyle of the ancestral apocritan, allowing more maneuverability of the female's ovipositor. The ovipositor either extends freely or is retracted, and may be developed into a stinger for both defense and paralyzing prey. Larvae are legless and blind, and either feed inside a host or in a nest cell provisioned by their mothers.
The superfamily Ichneumonoidea contains one extinct and three extant families, including the two largest families within Hymenoptera: Ichneumonidae and Braconidae. The group is thought to contain as many as 100,000 species, many of which have not yet been described. Like other parasitoid wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, now known to be paraphyletic.
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 sting their prey.
Conops quadrifasciatus, the yellow-banded conops, is a species of fly from the genus Conops in the family Conopidae.
Epiophlebia superstes, the Japanese relict dragonfly, is one of the four species of the genus Epiophlebia, belonging to the family Epiophlebiidae, which is itself the sole living representative of the epiproctan infraorder Epiophlebioptera.
Meloe violaceus, the violet oil beetle, is a species of oil beetle belonging to the family Meloidae subfamily Meloinae.
Amegilla quadrifasciata, the white-banded digger bee, is a species of bee belonging to the family Apidae subfamily Apinae.
Rhyssa persuasoria, also known as the sabre wasp, is a species belonging to the family Ichneumonidae subfamily Rhyssinae. Members of this subfamily, including those of Rhyssa and the allied Megarhyssa, are also known collectively as giant ichneumonid wasps or giant ichneumons.
Scolia hirta is a species of wasp in the subfamily Scoliinae of the family Scoliidae.
Mutilla europaea, the large velvet ant, is a species of parasitoid wasps belonging to the family Mutillidae. It is a parasitoid on various species of bumblebees and is found in Europe, Asia, and North Africa.
Amblyteles armatorius is a species of parasitic wasp in the family Ichneumonidae first described by Johann Reinhold Forster in 1771.
Coelioxys, common name leaf-cutting cuckoo bees or sharp-tailed bees, is a genus of solitary kleptoparasitic cuckoo bees belonging to the family Megachilidae.
Gonatopus clavipes is a species of small wasp in the family Dryinidae. It is a solitary wasp that superficially resembles an ant, and its larva is a parasitoid of leafhoppers in the subfamily Deltocephalinae. It has a Palearctic distribution, and within Europe parasitises at least eleven genera and thirty-one species of leafhopper.
Anoplius viaticus, commonly known as the black-banded spider wasp, is a species of spider wasp. These wasps are known as spider wasps because the females capture spiders to provide their offspring with food. The paralysed spider is cached in a burrow, the wasp lays an egg on it, and when this hatches, the developing wasp larva consumes the spider. This species is found in sandy heathland across most of Europe.
Symmorphus allobrogus is a species of potter wasps belonging to the subfamily Eumeninae.
Neoitamus cyanurus, the common awl robberfly, is a species of 'robber fly' belonging to the family Asilidae.
Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.
Chelostoma florisomne, the large scissor-bee, is a species of hymenopteran in the family Megachilidae.
Hylaeus relegatus is a bee species in the family Colletidae. It is endemic to New Zealand and was first described by Frederick Smith. It is the largest and most common species of this genus in that country. H. relegatus can be found throughout the three main islands of New Zealand and visits the flowers of a wide variety of plant species, both native and introduced. Although widespread, this species is not abundant at any one particular location. It has been hypothesised that human made nest sites can be used to increase its numbers.
