Families with mud dauber species

Mud dauber (or "mud wasp") 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 (especially the subfamily Eumeninae), 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. [1] 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.

The organ pipe mud dauber, one of many mud daubers in the family Crabronidae, builds nests in the shape of a cylindrical tube resembling an organ pipe or pan flute. Common sites include vertical or horizontal faces of walls, cliffs, bridges, overhangs and shelter caves or other structures.

The nest of a black and yellow mud dauber species Sceliphron caementarium is a simple, one, two or sometimes three celled, cigar-shaped mass that is attached to crevices, cracks and corners. Each cell contains one egg. Usually several cells are clumped together and covered in mud. The blue mud dauber species Chalybion californicum , another sphecid, builds mud nests, but occasionally refurbishes the abandoned nests of other species; it preys primarily on spiders. [2] The two species commonly occupy the same barns, porches, or other nest sites.

All mud daubers may occupy the same sites year after year, creating large numbers of nests in protected locations; such sites are often used as nest sites by other kinds of wasps and bees, as well as other types of insects.

One disadvantage to making nests is that most, if not all, of the nest-maker’s offspring are concentrated in one place, making them highly vulnerable to predation. Once a predator finds a nest, it can plunder it cell by cell. A variety of parasitic wasps, ranging from extremely tiny chalcidoid wasps to larger, bright green chrysidid wasps, attack mud dauber nests. They pirate provisions and offspring as food for their own offspring.

Food

Like most other solitary wasps, mud daubers are parasitoids, but unlike the majority of parasitoids, they actively capture and paralyze the prey upon which they lay their eggs. The females build the nests, and hunt to provision them. Males of pipe-organ mud daubers have been observed bringing spiders to the nest, and nest guarding, an extremely rare appearance of male parental care, otherwise virtually unknown among Hymenoptera.

Black and yellow mud daubers primarily prey on relatively small, colorful spiders, such as crab spiders (and related groups), orb weavers and some jumping spiders. They usually find them in and around vegetation. Blue mud daubers are the main predator of the black and brown widow spiders.

Adults of both sexes frequently drink flower nectar, but they stock their nests with spiders, which serve as food for their offspring. Mud daubers prefer particular kinds and sizes of spiders for their larders. Instead of stocking a nest cell with one or two large spiders, mud daubers cram as many as two dozen small spiders into a nest cell.

To capture a spider, the wasp grabs it and stings it. The venom from the sting does not kill the spider, but paralyzes and preserves it so it can be transported and stored in the nest cell until consumed by the larva. A mud dauber usually lays its egg on the prey item and then seals it into the nest cell with a mud cap. [1] It then builds another cell or nest. The young survive the winter inside the nest.

Airplane incidents

Florida Commuter Airlines Flight 65

On September 12, 1980, Florida Commuter Airlines Flight 65 crashed on a flight from Palm Beach International Airport to Grand Bahama International Airport, killing all 34 people on board. Before the flight, a mud dauber's nest was discovered in a pitot tube of the airplane which was cleaned by maintenance using an unapproved method. Although the NTSB could not determine the cause of the accident, one of the possible factors was the improper cleaning of the mud dauber nest from the pitot tube.

Birgenair Flight 301

On February 6, 1996, Birgenair Flight 301, a 757 jet flying from Puerto Plata in the Dominican Republic, crashed into the Atlantic Ocean. All 13 crew members and 176 passengers were killed. A key part of the accident was a blocked pitot tube. Although the tubes were never recovered from the ocean floor, the plane had been sitting on the tarmac for 25 days with uncovered pitot tubes. Investigators believe a black and yellow mud dauber, Sceliphron caementarium, got into the tube and built its cylindrical nest inside, causing faulty air-speed readings that were a large part of the crash.

Gulfstream N450KK

On April 10, 2015, about 18:45 Eastern Daylight Time, a Gulfstream Aerospace G-IV, N450KK, was substantially damaged during a cabin over-pressurization event over the Caribbean Sea while en route to Fort Lauderdale, Florida. An initial examination of the fuselage revealed that the outflow valve safety port, located on the outer fuselage, was completely plugged with a foreign material resembling dried soil from a mud dauber.

<i>Sceliphron</i> Genus of 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.

<span class="mw-page-title-main">Organ pipe mud dauber</span> Species of wasp

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. 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.

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.

<span class="mw-page-title-main">Wasp</span> Group of insects

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.

<i>Chalybion</i> Genus of wasps

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.

Sphecius grandis, also called the western cicada killer, is a species of cicada killer wasp (Sphecius). The western species shares the same nesting biology as its fellow species, the eastern cicada killer. S. grandis, like all other species of the genus Sphecius, mainly provides cicadas for its offspring. It forms nest aggregations and mates and broods once in a year, in July and early August. The wasp is on average 3 cm (1 in) to 5 cm (2 in) in length and is amber-yellow with yellow rings on its abdomen.

<i>Sceliphron curvatum</i> Species of wasp

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.

<i>Ammophila sabulosa</i> Species of wasp

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.

<span class="mw-page-title-main">Hunting wasp</span> Group of wasps defined by their behaviour

Hunting wasps are members of various taxa of the insect order Hymenoptera. Their habits and affinities vary in many ways, but all practise parental care of their larvae in that they capture prey, usually insects, to feed their larvae. Whether solitary or social, most species construct some form of protection or nest in which they hide the prey and in which the larvae can feed and pupate in reasonable security.

<i>Sceliphron laetum</i> Genus of 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.

Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.

Trypoxylon lactitarse is a species of square-headed wasp in the family Crabronidae. It is found in North, Central, and South America, and said to range from Canada to Argentina. These are fairly common harmless solitary wasps, although as with others of this same genus, the adult males can be observed to guard the nests. This species is well-characterised as nesting in pre-existing cavities which has facilitated ecological studies, as females can be easily attracted to nest in human-made trap-nests. Females construct a linear series of cells that are subdivided by mud partitions. In the south of range, nesting activity has been recorded to occur throughout the year, although may be more common in certain months. They can begin construction of their nests with a layer of mud, followed by the formation of a linear series of 6-8 cells.
