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. [1] It is the type species of the genus Pompilus and therefore of the family Pompilidae.
It is widespread throughout the Old World, including Mediterranean islands, Canary Islands, Madagascar, Sri Lanka, Japan, the Philippines, Borneo, Java, and Australia. In Britain, it is mainly found in the south, but extends north to the central belt of Scotland. [2]
P. cinereus is a highly variable species throughout its wide range, giving rise to the large number of synonyms which have been attached to the species by different authors. Where it overlaps with congeners in southern and central Africa and in southern Asia, the phenotype is stable and it can be distinguished from the species with which it is sympatric. Over the rest of its huge range, it has no sympatric congeners and shows wide phenotypic variation. [1]
For example, in western Europe, the females in north-western populations are predominantly black, pubescent dorsally with narrow transverse strips of grey at the rear of each tergum, interrupted medially. The face is dark above the antennae and grey below. Some of the specimens taken in Gotland, Sweden, are black with dark brown pubescence posteriorly on the abdomen, or with a little grey on that of others; these specimens are the basis of the 'subspecies' P. plumbeus gotlandicus Wolf. In northern Iberia, a dark form which is nearly identical with the form found around the North Sea and Baltic littoral is found, but with the face narrower above. In southern Portugal, individuals that are almost entirely black and were named as the subspecies P. c. lusitanicus are found and these are found in sympatry with more normally grey individuals previously regarded as P. c. plumbeus which is the characteristic form of south-east Spain and the rest of the Mediterranean. This type of phenotypic variability is found throughout the species range. [1] Day (1981) treats P. cinereus as a monotypic species despite this wide variation across its range. [1]
It is found in coastal dunes and sandy river beds and banks. [1] P. cinereus shows a distinct preference for loose sand and may be abundant in sheltered, sunny areas in dune systems. [3]
In northwestern Europe, spiders of the family Lycosidae are the most frequent prey for P. cinereus, spiders of the families Gnaphosidae, Miturgidae, Clubionidae, Pisauridae, and Thomisidae have also been recorded as prey, albeit with much less frequency than Lycosidae. [3] P. cinereus locates in the sand or encounters on the surface a prey individual which is stung into immobility. The prey is then transported by the wasp, which holds the prey in its mandibles and walks forwards. Most frequently, the prey is temporarily interred whilst a suitable nest site is sought and a burrow excavated. Significant time and effort may be spent on trial burrows before a site is finally selected. When the nest is complete, the prey may be taken to the entrance and carried in. The prey spider is carried into a terminal cell big enough to accommodate both wasp and prey. The egg is laid on the upper forward part the prey's abdomen. The wasp then closes the burrow, pulling in the walls and roof with its mandibles and then tamping the soil with the tip of the abdomen. The spider in the cell recovers from paralysis some time between 3 and 6 hours after being stung and begins to walk aimlessly about the cell, spinning silk continuously resulting in a silk-lined cell of considerable structural integrity. After three days, the small larva emerges from the egg [1] and begins to consume the trapped spider, killing it by consuming its abdomen. [3]
P. cinereus is ecologically versatile and takes a wide variety of prey and is the dominant pompilid spider wasp in many parts of its range. The smaller males hatch from unfertilised eggs (like other in Hymenoptera) and are provisioned with smaller spider prey than female eggs. [1]
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 prey. They are found on all continents other than 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.
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 is a genus of wasps in the family Pompilidae which prey on spiders. Nine species are found in Europe.
Episyron rufipes, the red-legged spider wasp, is a red and black or completely black spider-hunting wasp.
Episyron quinquenotatus, the white-trimmed black wasp, is a North American species of pompilid spider hunting wasp.
Pompilus is a genus of spider wasps in the family Pompilidae, the members of which prey on spiders. There are seven species recognised in Pompilus sensu stricto. It is the type genus of the family Pompilidae and the subfamily Pompilinae.
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.
Cryptocheilus notatus is the largest species of spider wasps (Pompilidae) to be found in Great Britain reaching up to 18mm in length.
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.
Sphictostethus nitidus, the golden hunter wasp or red spider wasp, is a species of pepsid spider wasp endemic to New Zealand.
Caliadurgus fasciatellus is a species of spider wasp from the subfamily Pepsinae found from Western Europe to the Far East of Asia.
Hemipepsis ustulata is a species of tarantula hawk wasp native to the Southwestern United States. Tarantula hawks are a large, conspicuous family of long-legged wasps which prey on tarantulas. They use their long legs to grapple with their prey before paralyzing them with a powerful sting. Their stings are ranked second-most painful in the insect world. They are solitary, displaying lekking territorial behavior in their mating rituals.
Priochilus captivum is a species of neotropical spider wasp in the family Pompilidae. It is native to Central and South America. It was first described by the Danish zoologist Johan Christian Fabricius in 1804.
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.
Anoplius concinnus is a widespread Eurasian species of spider wasp.
Tachypompilus ferrugineus, the rusty spider wasp, red-tailed spider hunter, or sometimes red-tailed spider wasp is a species of spider wasp from the Americas. It preys mainly on wandering spiders, especially wolf spiders.
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.
