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. [2] This species is found in sandy heathland across most of Europe.
A. viaticus is a large species of spider-hunting wasp and measures about 14 millimetres (0.55 in) in length. [3] The head and thorax are black and the propodeum is fused to the thorax and bears erect black hairs. The first three terga of the abdomen are red with black rear margins and the remainder of the abdomen is black. [4]
Adult A. viaticus feed on nectar from flowers. Wasps in this species predominantly prey on spiders from the wolf spider family Lycosidae, but they also take ground spiders (Gnaphosidae), grass spiders (Agelenidae), crab spiders (Thomisidae) and jumping spiders (Salticidae). [5]
Anoplius viaticus is unusual in that it overwinters as an adult, hibernating in a deep burrow. This enables it to emerge and become active earlier in the year than other related species. In southern England, it is on the wing from March onwards. [3]
The female A. viaticus searches for a suitable spider with which to provision its nest. The spider is injected with venom to paralyse it and is dragged back to the chosen nesting location. The wasp puts the spider down and digs a shallow burrow. The spider is then dragged into the burrow, the wasp lays an egg on its still-living body and plugs the burrow with soil. Further similar single cell nests are excavated and provisioned, usually in close proximity to the first. [6]
Things do not always go according to plan. Other female wasps may try to steal the prey before it is brought to the nest site, or they may take it while the nest is being excavated. Wasps have been observed to deposit their paralysed prey in grassy areas, where it is perhaps less visible to conspecifics, while the nest burrow is dug. Even after the burrow is sealed, it is not entirely safe, as other wasps may try to unseal it and lay their eggs on the prey, a practice known as brood parasitism. Female wasps defend their nesting site and drive away conspecifics that come too close. They seem to be concerned for the safety of their future offspring because they frequently interrupt their hunting to return to the nest site, and the clustering of the burrows makes their defence easier. [6]
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host. They are found on all continents other than Europe and Antarctica.
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.
The European beewolf, also known as the bee-killer wasp or the bee-eating philanthus, is a solitary wasp that lives in the Western Palearctic and Afrotropics. Although the adults of the species are herbivores, the species derives its name from the behaviour of the inseminated females, who hunt Western honey bees. The female places several of its paralysed prey together with an egg in a small underground chamber, to serve as food for the wasp larvae. All members of the genus Philanthus hunt various species of bees, but P. triangulum is apparently the only one that specialises in Western honey bees.
Bembix rostrata is a species of sand wasp native to Central Europe. The genus Bembix - of which B. rostrata is among the most distinctive species - has over 340 species worldwide and is found mostly in warm regions with open, sandy soils; Australia and Africa have a particularly rich variety of species.
Philanthus gibbosus, which is commonly referred to as a beewolf due to its predation practices, is a species of bee-hunting wasp and is the most common and widespread member of the genus in North America. P. gibbosus is of the order Hymenoptera and the genus Philanthus. It is native to the Midwestern United States and the western Appalachians. P. gibbosus are often observed to visit flowers and other plants in search of insect prey to feed their young. The prey that P. gibbosus catches is then coated in a layer of pollen and fed to the young wasps.
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.
Ammophila sabulosa, the red-banded sand wasp, is a species of the subfamily Ammophilinae of the solitary hunting wasp family Sphecidae, also called digger wasps. Found across Eurasia, the parasitoid wasp is notable for the mass provisioning behaviour of the females, hunting caterpillars mainly on sunny days, paralysing them with a sting, and burying them in a burrow with a single egg. The species is also remarkable for the extent to which females parasitise their own species, either stealing prey from nests of other females to provision their own nests, or in brood parasitism, removing the other female's egg and laying one of her own instead.
Episyron quinquenotatus, the white-trimmed black wasp, is a North American species of pompilid spider hunting wasp.
Cryptocheilus bicolor is a large, strikingly coloured spider wasp from Australia.
Sphictostethus nitidus, the golden hunter wasp or red spider wasp, is a species of pepsid spider wasp endemic to New Zealand.
Ammophila urnaria is a species of hunting wasp in the family Sphecidae. It is a black and red insect native to the eastern United States. It feeds on nectar but catches and paralyses caterpillars to leave in underground chambers for its developing larvae to consume.
Polistes biglumis is a species of social wasp within Polistes, the most common genus of paper wasp. It is distinguished mainly by its tendency to reside in montane climates in meadows or alpine areas. Selection pressure from the wasp's environment has led to several idiosyncrasies of its behavior and lifecycle with respect to its relative species in the genus Polistes. It alone among paper wasps is often polyandrous. In addition, it has a truncated nesting season that gives rise to unique competitive dynamics among females of the species. P. biglumis wasps use an odor-based recognition system that is the basis for all wasp-to-wasp interaction of the species. The wasp's lifecycle is highly intertwined with that of Polistes atrimandibularis, an obligate social parasite wasp that frequently invades the combs of P. biglumis wasps.
Sceliphron laetum is a wasp in the family Sphecidae, the mud-dauber wasps. Like other members of this genus, it is a solitary species and builds cells out of mud in which to rear its young, provisioning them with paralysed spiders, and laying an egg in each. This wasp is native to Australia and southeastern Asia.
Podalonia hirsuta is a species of parasitoidal wasps in the family Sphecidae.
Anoplius infuscatus is a species of spider wasp found mainly in Eurasia.
Anoplius concinnus is a widespread Eurasian species of spider wasp.
Poecilopompilus algidus is a species of spider wasp which is widespread in the Americas.
Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.
Sceliphron asiaticum is a species of thread-waisted wasp in the family Sphecidae. It is native to the Neotropics, South America and the Caribbean region.
Ceropales bipunctata, the Two-Speckled Cuckoo Spider Wasp, is a species of diurnal, kleptoparasitic spider wasp in the family Pompilidae. It is an obligate kleptoparasite, meaning that it must rely on the captured provisions of other spider wasps and cannot capture its own. It is found on the Atlantic Coast of North America, north to New Brunswick, Canada. It feeds on nectar primarily from goldenrods, and also other common nectaring plants. It is known to lay an egg on the prey of other pompilids, including the two species Anoplius cleora and Anoplius aethiops. Eggs are laid in the book lung of the spider. These wasps also sometimes lay an egg on prey from spider-hunting wasps in the family Sphecidae.
