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.
Bembix rostrata ranges in distribution from Europe and the Mediterranean to Central Asia, and as far north as Denmark and Sweden.
Bembix rostrata displays distinctive behaviour in front of its nest, digging its burrows with fast, synchronised movements of its forelegs. In addition, the insect can turn very rapidly about its own axis, the flapping of its wings as it does this producing a buzzing sound reminiscent of a gyroscope. Its size (15–24 mm or 0.59–0.94 in), striking yellow and black-striped abdomen and the labrum, extended into a narrow beak, are distinctive features.
Bembix rostrata goes through 4 general life stages: egg, larva, pupa, and adult. Adult females burrow nests into the sand and lay their eggs there. Once the eggs hatch, the new larvae continue their development in the nests that they were born in. Each individual grub develops in its own burrow, this reduces competition for development space and necessary nutrients. Adult B. rostrata gather prey and bring the food back for the developing grubs to feed on. When the young reach the pupal stage, females dig another nest to lay more eggs.
Bembix rostrata forms colonies between a dozen and several hundred insects, where the females each construct a tube up to 20 cm (7.9 in) long containing a single brood cell. This is stocked with dozens of insects, predominantly large flies (Tabanidae, Syrphidae), which provide the larva with food for its two-week development to the imago stage. The female carefully re-seals the nest tube after each feeding. Because of this intensive maternal care, a female can raise at most only eight larvae during the high summer. B. rostata is very faithful to its nest sites, often nesting in the same places year-on-year, even if these change over time and alternative habitats are available.
The species has become rare due to loss of large open-sand surfaces in warm areas, such as in the sand dunes of the upper Rhine Graben. It is also the host for several parasitoids in families such as Bombyliidae, Conopidae, and Mutillidae. A cuckoo wasp which specialises in B. rostrata is Parnopes grandior .
The behaviour of B. rostrata led the famous naturalist Jean-Henri Fabre to conduct intensive studies of the species.
Paper wasps are a type of vespid wasps. The term is typically used to refer to members of the vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae and Stenogastrinae, which also make nests out of paper.
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.
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.
Sphecius speciosus, the eastern cicada-killer wasp, is a large, solitary digger wasp species in the family Bembicidae. They are so named because they hunt cicadas and provision their nests with them. Cicada killers exert a measure of natural control on cicada populations, and as such, they may directly benefit the deciduous trees upon which the cicadas feed. Sometimes, they are erroneously called sand hornets, despite not truly being hornets, which belong to the family Vespidae.
The Sphecidae are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps.
Sceliphron, also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud. Nests are frequently constructed in shaded niches, often just inside of windows or vent openings, and it may take a female only a day to construct a cell requiring dozens of trips carrying mud. Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. Females of some species lay a modest average of 15 eggs over their whole lifespan. Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging.
The Bembicini, or sand wasps, are a large tribe of bembecid wasps, comprising 20 genera. Bembicines are predators on various groups of insects. The type of prey captured tends to be rather consistent within each genus, with flies (Diptera) being the most common type of prey taken. Nests are typically short, simple burrows, with a single enlarged chamber at the bottom which is stocked with freshly paralysed prey items for the developing wasp larva; the egg may sometimes be laid before the chamber is completely stocked. It is common for numerous females to excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations, which tend to attract various species of parasitic flies and wasps, many of which are cleptoparasites; in some cases, the sand wasps prey on their own parasites (e.g.,), a surprisingly rare phenomenon in the animal kingdom. Although sand wasps are normally yellow and black, some are black and white with bright green eyes.
Philanthidae is one of the largest families of wasp in the superfamily Apoidea, with 1167 species in 8 genera, most of which are Cerceris.
Philanthus gibbosus, the hump-backed beewolf, 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.
Cerceris fumipennis, the only species of buprestid-hunting Philanthidae occurring in eastern North America, is found throughout the continental United States east of the Rockies: from Texas and Florida north to Maine, Wyoming, and into Canada. The wasps most often nest in open areas of hard-packed sandy soil surrounded by woody habitat suitable for their buprestid beetle prey.
Sphex pensylvanicus, the great black wasp, is a species of digger wasp. It lives across most of North America and grows to a size of 20–35 mm (0.8–1.4 in). The larvae feed on living insects that the females paralyze and carry to the underground nest.
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.
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.
Chrysis ignita is a species of cuckoo wasp. It is one of a group of species which are difficult to separate and which may be referred to as ruby-tailed wasps.
Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.
Cerceris rybyensis, the ornate tailed digger wasp, is a Palearctic species of solitary wasp from the family Philanthidae which specialised in hunting small to medium-sized mining bees. It is the type species of the genus Cerceris and was named as Sphex rybyensis by Carl Linnaeus in 1771.
Ammophila placida is a species of thread-waisted wasp in the family Sphecidae. It is found in the continental United States and Central America.
Palmodes occitanicus is a species of thread-waisted wasp in the family Sphecidae.
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.
