Sphecius speciosus, often simply referred to as the cicada killer or the cicada hawk, is a large, solitary digger wasp species in the family Crabronidae. The name may be applied to any species of crabronid that preys on cicadas, though in North America, it is typically applied to this species, also referred to as the eastern cicada killer in order to further differentiate it from the multiple other examples of related wasp species. Sometimes, they are called sand hornets, although they are not hornets, which belong to the family Vespidae. This species can be found in the Eastern and Midwest U.S. and southwards into Mexico and Central America. 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.
The median wasp is a species of social wasp of the family Vespidae found throughout Europe and Asia. It builds aerial paper nests often in shrubs or trees, and occasionally under the eaves of buildings. It is most common to see this wasp between May and October during its 3.3 month colony cycle. Behaviours of this wasp include nest defense, curling which is believed to function in brood incubation, and gastral vibration which is involved in larval feeding. The median wasp has a halplodiploid sex determination system that results in a high level of relatedness within the colony. This species is not usually aggressive but will sting if they feel their nest is threatened. Most foraging in the nest is done by the workers once the first ones reach adulthood. These workers forage for insects, nectar, and wood for nest construction in temperatures as low as 7 °C (45 °F). The median wasp is known to be occasionally affected by the fungus Cordyceps sphecocephala and the Cricket paralysis virus.
The organ pipe mud dauber is a predatory wasp in the family Crabronidae. They are fairly large wasps, ranging from 3.9–5.1 cm, and have been recorded to fly from May to September. Female and male are similar in colour, a shiny black, with the end part of the back leg being pale yellow to white. The organ pipe mud dauber feeds mainly on three genera of spider: Neoscona, Araneus, and Eustala. Melittobia, a parasitoid wasp, is a common ectoparasite of T. politum prepupae. Other sources of parasitism include the Bombyliid fly Anthrax, Chrysidid wasps, and various species of scavenger flies (Miltogramminae). The tufted titmouse is a known predator of T. politum, and may feed on them more commonly than previously thought as the holes made by the titmouse are similar in shape and size to those made by T. politum leaving the nest after pupation.
Volucella pellucens, the pellucid fly, is a hoverfly.
Vespula vulgaris, known as the Common wasp, is a species found in regions that include the United Kingdom, Ireland, Germany, India, China, New Zealand and Australia. It is sometimes known in English as the European wasp, but the same name is used for the species Vespula germanica or German wasp. In 2010, the ostensible Vespula vulgaris wasps in North America were found to be a different species, Vespula alascensis.
Osmia lignaria, commonly known as the orchard mason bee or blue orchard bee, is a megachilid bee that makes nests in natural holes and reeds, creating individual cells for its brood that are separated by mud dividers. Unlike carpenter bees, it cannot drill holes in wood. O. lignaria is a common species used for early spring fruit bloom in the United States and Canada, though a number of other Osmia species are cultured for use in pollination.
The Bembicini, or sand wasps, are a large tribe of crabronid 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, 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.
The subfamily Philanthinae is one of the largest groups in the wasp family Crabronidae, with about 1100 species in 9 genera, most of them in Cerceris; Alexander treats it as having only 8 genera. Historically, this subfamily has frequently been accorded family status. The subfamily consists of solitary, predatory wasps, each genus having its own distinct and consistent prey preferences. The adult females dig tunnels in the ground for nesting.
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.
Mass provisioning is a form of parental investment in which an adult insect, most commonly a hymenopteran such as a bee or wasp, stocks all the food for each of her offspring in a small chamber before she lays the egg. This behavior is common in both solitary and eusocial bees, though essentially absent in eusocial 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.
The subfamily Pemphredoninae also known as the aphid wasps, is a large group in the wasp family Crabronidae, with over 1000 species. Historically, this subfamily has frequently been accorded family status. In some recent phylogenetic analyses, one of the subtribes within this group is the sister lineage to the superfamily Apoidea, and accorded family rank as Ammoplanidae along with Pemphredonidae and Psenidae so as to keep families monophyletic.
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.
The thin-waisted social wasps, which typically reside in Neotropical regions from Central to South America, are a small genus of wasps that build nests and live in colonies ranging in size from 1 to 18 members. Microstigmus is widely considered to be the only true eusocial species within the family Crabronidae. Like all Hymenoptera, Microstigmus has an interesting sex determination pattern. Females are 2n (diploid), spawning from eggs that have been fertilized, while males are 1n (haploid) and spawn from unfertilized eggs. Female wasps contain the eggs within their egg sac and have the option of fertilizing them or not, thus having complete control of the gender of their offspring. This wasp genus, part of the suborder Apocrita, is distinguished physically by the narrow waist (petiole) between the end segment of the thorax (mesosoma) and the beginning of the abdomen (metasoma). Specifically, it is in the subgroup of "apoid wasps", those that exhibit social behavior in nesting and foraging. Evidence does exist that in some species social altruism is visible; however, studies on these topics have been limited. The small size and enclosed nest structure makes it difficult to obtain significant data. Although it was originally classified under the Sphecidae family due to its elongated petiole, Microstigmus has been reclassified into the new Crabronidae family.
Structures built by non-human animals, often called animal architecture, are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of 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.
Polistes fuscatus, whose common name is the dark or northern paper wasp, is widely found in eastern North America, from southern Canada through the southern United States. It often nests around human development. However, it greatly prefers areas in which wood is readily available for use as nest material, therefore they are also found near and in woodlands and savannas. P. fuscatus is a social wasp that is part of a complex society based around a single dominant foundress along with other cofoundresses and a dominance hierarchy.
Hyperalonia morio is a species of bee flies in the family Bombyliidae.
Tachytes is a genus of predatory, solitary wasps, containing about 300 species.
Stigmus americanus is a species of aphid wasp in the family Crabronidae. It is found in North America.
