Dipogon bifasciatus is a spider wasp from the family Pompilidae.
An all-black species with bifasciate wings, the generic name, Dipogon "two beards", refers to the tufts of forward-pointing bristles on the maxilla of the female, the purpose of which is to pack the nest entrance with old spider silk. [2] Females grow to 5–9 mm in length, and males 4–7 mm.
These spider wasps are found in southern Britain [3] through Europe to Russia [4] and on to Japan. In Europe, the southern limits are in Italy and Bulgaria.
Open wooded areas such as forest edge, scrub, orchards and vineyards. They will use gardens.
Dipogon bifasciatus hunts crab spiders, of the family Thomisidae, in Britain Xysticus cristatus has been observed as a prey item. [2] The prey are stored in cells created in old insect burrows dug into rotting wood, hollow stems and cracks in walls, and, unlike many other Pompilid spider wasps, these may be clustered with six cells in each burrow. A single egg is laid on each paralysed crab spider, smaller spiders host males and larger females. The nest is made up of sawdust, plant fibres and dismembered insect parts bound together with spider silk and sealed with chewed wood. [2]
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.
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.
Structures built by animals, often called animal architecture, abound in nature. Examples of animal structures include termite mounds, wasp and beehives, burrow complexes of rodents, beaver dams, elaborate nests of birds, and webs of spiders.
Episyron rufipes, the red-legged spider wasp, is a red and black or completely black spider-hunting wasp.
Pompilus cinereus, the leaden spider wasp is the most widespread species of the Pompilus spider wasps, and throughout a large proportion of its wide distribution is the only species of Pompilus. It is the type species of the genus Pompilus and therefore of the family Pompilidae.
Dipogon is a genus of spider wasps of the family Pompilidae in the subfamily Pepsinae. They are found in Europe, Asia, and North America. Their generic name comes from the characteristic long bristle tufts just below the mandibles, which are used to carry material to construct the cells in the nest, and for constructing the nest.
Dipogon subintermedius is a spider wasp from the family Pompilidae.
Dipogon variegatus is a pompilid spider wasp in the subfamily Pepsinae from the Palearctic.
Auplopus carbonarius is a spider wasp of the family Pompilidae. Uniquely among the British group it constructs a nest of barrel-shaped cells in which spiders are stored and the larvae develop.
Anoplius nigerrimus is one of the most common spider wasps, or pompilids, in Europe. They are mostly black and the females are 6–8 mm long while males measure 5–8 mm. This species may be distinguished from the related Anoplius concinnus and Anoplius caviventris by the 20 setae, or hairs, on the forehead rather than 60 or 45.
Priocnemis monachus is a large spider wasp from New Zealand where it is known as the "black hunting wasp". It is the largest pompilid in New Zealand.
Cryptocheilus australis, the golden spider wasp, is an Australian pepsid spider wasp that was accidentally introduced to New Zealand around 1960.
Sphictostethus nitidus, the golden hunter wasp or red spider wasp, is a species of pepsid spider wasp endemic to New Zealand.
Agenioideus cinctellus is a spider wasp of the subfamily Pompilinae with a Palearctic distribution.
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.
Anoplius infuscatus is a species of spider wasp found mainly in Eurasia.
Poecilopompilus algidus is a species of spider wasp which is widespread in the Americas.
Pepsis grossa is a very large species of pepsine spider wasp from the southern part of North America, south to northern South America. It preys on tarantula spiders, giving rise to the name tarantula hawk for the wasps in the genus Pepsis and the related Hemipepsis. Only the females hunt, so only they are capable of delivering a sting, which is considered the second most painful of any insect sting; scoring 4.0 on the Schmidt sting pain index compared to the bullet ant's 4.0+. It is the state insect of New Mexico. The colour morphs are the xanthic orange-winged form and the melanic black winged form. In northern South America, a third form, known as "lygamorphic", has a dark base to the wings which have dark amber median patches and a pale tip.
Xysticus cristatus, the common crab spider, is a European spider from the family Thomisidae.
Dipogon sayi is a species of spider wasp of the family Pompilidae.
