The Sphecidae are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps.
Mud dauber is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae which build their nests from mud; this excludes members of the family Vespidae, which are instead referred to as "potter wasps". Mud daubers are variable in appearance. Most are long, slender wasps about 1 inch (25 mm) in length. The name refers to the nests that are made by the female wasps, which consist of mud molded into place by the wasp's mandibles. Mud daubers are not normally aggressive, but can become belligerent when threatened. Stings are uncommon.
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 organ pipe mud dauber is a predatory wasp in the family Crabronidae. It is fairly large, ranging from 3.9–5.1 cm, and has been recorded to fly from May to September. Females and males are similar in colour, a shiny black, with the end part of the back leg being pale yellow to white.
Potter wasps, the Eumeninae, are a cosmopolitan wasp group presently considered a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae.
Chalybion californicum, the common blue mud dauber of North America, is a metallic blue species of mud dauber wasp first described by Henri Louis Frédéric de Saussure in 1867. It is not normally aggressive towards humans. It is similar in shape and colour to the steel-blue cricket hunter. Like other types of wasps, males do not have an ovipositor, and therefore cannot sting. It is ranged from northern Mexico to southern Canada, including most of the United States. It has also been introduced to regions including Hawaii, Bermuda, Croatia and other European countries.
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.
Sceliphron spirifex is a species of sphecid wasp. It has a medium-sized body, which is dull black with a long, yellow petiole (waist). The legs are black with yellow bands, the antennae are black and the wings are clear.
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.
Microstigmus, or the thin-waisted social wasps, is a small genus wasp in the family Pemphredonidae. This genus is found in the Neotropical realm from Central to South America. They 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 of apoid wasp.
Chalybion is a genus of blue mud dauber wasps in the family Sphecidae. Chalybion species nest in a wide range of natural and artificial cavities such as holes in wood, walls, plant stems, etc., where they typically provision their brood cells with paralyzed spiders. They also reuse old nests of other wasps like Trypoxylon and Sceliphron.
Sceliphron curvatum, also known as the Asian mud-dauber wasp, is an insect in the genus Sceliphron of the wasp family Sphecidae. Like all wasps of this genus, it is a solitary species and builds nests out of mud. S. curvatum is native to some regions of Asia and invasive to Europe.
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.
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.
Acroricnus seductor is a species of wasp belonging to the family Ichneumonidae.
Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, native to Australia and found throughout New Zealand where it is an introduced species.
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.
Chalybion bengalense, also known as the oriental mud dauber, is a widely distributed member of the Chalybion genus. Melittobia assemi has been reported as a parasite of this species.
