Dolichovespula arenaria, also known as the common aerial yellowjacket , sandhills hornet, and common yellow hornet, is a species of wasp within the genus Dolichovespula widely distributed in the North American continent. [1] [2] [3]
The genus Dolichovespula is in the family Vespidae. In North America, the genus is referred to as yellowjackets. [4] The genus has 18 species, including D. arenaria and other species such as D. albida, D. alpicola, D. saxonica , and D. maculata . [1] [5]
D. arenaria can be identified by the medially interrupted or incised apical fasciae of terga 1 and 2. [6] They are yellow in color and can be differentiated from the other yellow-colored wasps, such as D. adulterina, in its genus by the lack of black markings in the ocular sinus. [6] In the majority of the population, the ocular sinus is yellow, but some melanic males have a black area that reaches the lower margin of the sinus. The queen has large black discal spots on terga 4 and 5, and smaller ones on terga 2 and 3. [6] Males can be identified by the larger antenna, spots on their basal band on terga 4 and 5 as well as an abdomen that ends with a flat "fuzzy butt" instead of a pointed stinger. [6] Nest size ranges from 1-6 combs, and are made out of dull grey paper. However, color variations do occasionally occur due to available materials. [4]
The common aerial yellowjacket lives across Canada and the United States. [1] [7] It occurs from northcentral Alaska to as far south as New Mexico and Arizona. D. arenaria is in fact one of the most common aerial yellowjackets found in eastern North America, [6] and nests can be found in arboreal to subterranean habitats. Its nests are made from paper-like material and are usually found in trees and shrubs. In urban settings, nests are frequently found on buildings. [4]
A queen initiates a colony in the spring by choosing a site and building a small paper nest where it lays its eggs. Then, the eggs hatch from the brood cell and the queen feeds the larvae. [8] These larvae eventually become workers and the colony continues to grow and peaks in the summer. [8] The workers are morphologically distinct from the queen. The single queen heads the annual nests by producing workers In the Dolichovespula genus, male (drone) production by workers is common and there exists high worker relatedness due to low effective paternity within nests. [9] In general, these colonies flourish for roughly a year before they dwindle as the winter sets in. [8]
Because yellow hornets generally locate their nests high in trees, their primary predators are fairly limited to birds and occasionally other wasps. Also, many mammals take the opportunity to go after an ill-placed nest to eat the nutrient-rich larvae. These would include skunks, opossums, raccoons, and bears. [4]
D. arenaria workers are known to mostly prey on live arthropods of a wide variety such as grasshoppers, crickets, caterpillars, spiders, flies, lacewings, and even lady beetles (which are generally avoided by Vespula species). [4] They also prey on larvae of the fall webworm, as well as young hummingbirds. In general, they are not attracted to protein baits. Occasionally, however, Dolichovespula spp. may feed on animal carcasses— such feeding has been observed on carcasses of a dog, pig, and snake. [4] They are commonly seen to prey in higher trees (2–4 m). [10]
In general, smaller colonies are seen as less aggressive than larger ones. Observations of D. arenaria’s personality differ, one stating that they are quarrelsome and then other arguing that they are not, [4] but this difference may lie in the fact that the first observation was observing the behavior when approaching a D. arenaria nest, whereas the other was describing the behavior of workers away from their nest individually. Smaller colonies’ colony defense behaviors are said to be unpredictable and erratic. [4]
Unique to D. arenaria is the observed spraying of venom out of their stings that has been seen from workers in large colonies. The "spray sting type", the term given to the venom-ejecting mechanism of these wasps, involves the contraction of the venom reservoir muscles. [4] This venom spraying mechanism allows for a greater release of alarm pheromone in the venom, which is key to elicit the attack behavior of yellowjackets. [11]
The two common parasites of D. arenaria nests are Sphecophaga vesparum burra, an ichneumonid, and D. arctica , a vespid social parasite. [4]
Female bee moths ( Aphomia sociella ) have also been known to lay their eggs in D. arenaria nests. The hatched larvae then proceed to feed on the eggs, larvae, and pupae left unprotected by the yellowjackets, sometimes destroying large parts of the nest as they tunnel throughout looking for food. [12]
The rates of S. v. burra parasitism are low and their existence within the nest does not appear to hinder colony development. [4] In this aspect, D. arenaria is unique among Dolichovespula spp. studied.
D. arctica is not well known, and has historically been confused with Dolichovespula adulterina, a palearctic species. [13] These wasps are inquilines, and rely on the workers of their host nests to rear offspring since they do not have their own worker caste. The parasite kills the foundress queen before the production of her workers is complete and takes over the nest. The lifespan of the parasite after the host queen's death is limited. [4]
Yellowjacket or yellow jacket is the common name in North America for predatory social wasps of the genera Vespula and Dolichovespula. Members of these genera are known simply as "wasps" in other English-speaking countries. Most of these are black and yellow like the eastern yellowjacket and the aerial yellowjacket ; some are black and white like the bald-faced hornet. Some have an abdomen with a red background color instead of black. They can be identified by their distinctive markings, their occurrence only in colonies, and a characteristic, rapid, side-to-side flight pattern prior to landing. All females are capable of stinging. Yellowjackets are important predators of pest insects.
Vespula is a small genus of social wasps, widely distributed in the Northern Hemisphere. Along with members of their sister genus Dolichovespula, they are collectively known by the common name yellowjackets in North America. Vespula species have a shorter oculomalar space and a more pronounced tendency to nest underground than Dolichovespula.
Dolichovespula maculata is a species of wasp in the genus Dolichovespula and a member of the eusocial, cosmopolitan family Vespidae. It is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and bull wasp. Technically a species of yellowjacket wasp, it is not one of the true hornets, which are in the genus Vespa. Colonies contain 400 to 700 workers, the largest recorded colony size in its genus, Dolichovespula. It builds a characteristic large hanging paper nest up to 58 cm (23 in) in length. Workers aggressively defend their nest by repeatedly stinging invaders.
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.
Vespula germanica, the European wasp, German wasp, or German yellowjacket, is a species of wasp found in much of the Northern Hemisphere, native to Europe, Northern Africa, and temperate Asia. It has spread and become well-established in many other places, including North America, South America, Australia, South Africa, and New Zealand. German wasps are part of the family Vespidae and are sometimes mistakenly referred to as paper wasps because they build grey paper nests, although strictly speaking, paper wasps are part of the subfamily Polistinae. In North America, they are also known as yellowjackets.
In 1909, the entomologist Carlo Emery noted that social parasites among insects tend to be parasites of species or genera to which they are closely related. Over time, this pattern has been recognized in many additional cases, and generalized to what is now known as Emery's rule. The pattern is best known for various taxa of Hymenoptera. For example, the social wasp Dolichovespula adulterina parasitizes other members of its genus such as Dolichovespula norwegica and Dolichovespula arenaria. Emery's rule is also applicable to members of other kingdoms such as fungi, red algae, and mistletoe. The significance and general relevance of this pattern are still a matter of some debate, as a great many exceptions exist, though a common explanation for the phenomenon when it occurs is that the parasites may have started as facultative parasites within the host species itself, but later became reproductively isolated and split off from the ancestral species, a form of sympatric speciation.
Dolichovespula is a small genus of social wasps distributed widely throughout the Northern Hemisphere. The yellow and black members of the genus are known by the common name yellowjackets in North America, such as Dolichovespula norwegica, along with members of their sister genus Vespula. In a study on the nesting biology of Dolichovespula, a colony of D. maculata with 771 workers was reported as having the largest recorded population count.
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.
Vespula pensylvanica, the western yellowjacket, is a Nearctic species of wasp in the genus Vespula. It is native to regions of North America, largely in areas with northern temperate climates. Its reproductive behavior is constrained by cold weather, which successfully reduces the number of western yellowjackets in cold months. However, in the absence of cold weather, this wasp's population can explode. The western yellowjacket has become particularly invasive in the Hawaiian Islands, resulting in their label as a major pest.
The eastern yellow jacket or eastern yellowjacket is a wasp found in eastern North America. Although most of their nests are subterranean, they are often considered a pest due to their nesting in recreational areas and buildings. This yellow jacket is a social insect, living in colonies of hundreds to thousands of individuals. Along with their subfamily, Vespinae, this species demonstrates supportive parental care for offspring, separation of reproductive and sterile castes, and overlapping generations. They aggressively defend their hives from threats and are known to inflict painful stings.
Dolichovespula saxonica, also known as the Saxon wasp, is a common social wasp found in the Palearctic region, specifically in large parts of Europe and in northern and central Asia. Although originally from continental Europe, D. saxonica has since colonised Britain, mainly in the south and east, but has been recorded as far north as East Lothian, Scotland. Most of their nests are above ground in trees and bushes, but they can also be found in buildings. Due to the proliferation of nests in urban areas and near residential homes, D. saxonica can be a pest for people. As a result, many human interventions are in place to remove Saxon nests. D. saxonica has been found to use chemical signaling in a lot of behaviours, such as alarm calls, fertility cues, and chemical trails.
The Norwegian wasp is a species of eusocial wasp. It is common in Scandinavia and can also be found in Scotland and other areas in Britain and Ireland. Often known for being a tree wasp, it nests in low branches and bushes and feeds on insects. It also obtains nectar from blueberry and snowberry flowers. Although D. norwegica is rarely considered a pest in the past, a few cases of pest problems relating to them have been reported. The species is not endangered.
The tree wasp is a species of eusocial wasp in the family Vespidae, found in the temperate regions of Eurasia, particularly in western Europe. Despite being called the tree wasp, it builds both aerial and underground paper nests, and can be found in rural and urban habitats. D. sylvestris is a medium-sized wasp that has yellow and black stripes and a black dot in the center of its clypeus. It is most common to see this wasp between May and September during its 3.5 month colony cycle.
Dolichovespula adulterina is a species of parasitic social wasp found in the Palearctic region. D. adulterina feeds on a variety of foods, including insects, spiders, arthropods, meat, molluscs, fruit, nectar, and larval secretions. D. adulterina was formerly considered to be synonymous with D. arctica from the Holarctic region, but more recent research indicates that D. arctica is a separate species.
Vespula rufa, commonly known as the red wasp, is a social wasp species belonging to the genus Vespula. It is found in northern and central Europe, parts of Asia, and northern parts of North America. Vespula rufa is characterised by red-brown markings and body segmentation, with the appearance varying amongst the different roles of individuals in the species. These wasps build small nests in dry banks underground that are not far below the surface. The colony cycle begins in the fall. Vespula rufa feed on live insects. One interesting fact about Vespula rufa is that the queen policing occurs in the species, and that worker policing occurs at much lower rates than other species in the genus Vespula. There are predators and parasites of the species. The species goes through a series of events before leaving the nest.
Vespula austriaca is an obligate parasitic wasp, parasitizing the nests of other species in the genus Vespula in the Old World. Its common host species include V. rufa in Europe, Japan, and East Siberia.V. austriaca wasps pollinate orchids.
Vespula acadica, also known as the Forest Yellowjacket, is a North American species of eusocial wasp which is part of the "rufa" group within the genus Vespula. It is a black and yellow wasp that is found in arboreal areas and builds its nests most often in decaying vegetation like logs, but has occasionally been found to build aerial nests. Due to its preference for forests V. acadica does not normally come into contact with humans; however, when colonies are disturbed, workers of this yellowjacket may be quite aggressive and persistent and sting repeatedly.
Vespula squamosa, or the southern yellowjacket, is a social wasp. This species can be identified by its distinctive black and yellow patterning and orange queen. This species is typically found in eastern North America, and its territory extends as far south as Central America. Within these territories, they create enormous, multiple-comb nests. The colonies may be either annual or perennial depending on the climate, and in many perennial nests, polygyny takes place. In addition, this species uses pheromones both as a sexual attractant and an alarm signal. This species feeds on insects and animal carcasses; it does not produce honey. V. squamosa, a social insect, has developed a parasitic relationship with the species V. vidua and V. maculifrons. Due to their painful, venomous stings, the species is considered a pest.
Vespula atropilosa, also known as the prairie yellowjacket, is a black and yellow social wasp that forms annual colonies. Vespula atropilosa was formerly a member of the Vespa family. Males have either xanthic (yellow) or melanic (black) abdominal coloring. The prairie yellowjacket can be found in the Western and Midwestern United States as well as parts of southern Canada. It builds its nests underground and prefers large open areas such as pastures and golf courses. Vespula atropilosa colonies are founded by a queen in the spring and grow most during mid-summer. It preys on other insects such as flies and grasshoppers but is not a scavenger like other wasps. Queens mate with multiple males, and males will fight each other for matings. V. atropilosa is a social wasp that practices altruism. Prairie yellowjackets are not considered pests but are commonly found in backyards in the Pacific Northwest. This species derives its common name from the prairies and grasslands where it can be found.
Vespula infernalis is an obligate parasitic wasp, parasitizing the nests of other species in the genus Vespula. Its common host species is V. acadica in North America. It is sometimes called the cuckoo yellowjacket wasp due to its inquiline lifestyle. They differ from other parasitic wasps in their intensely aggressive behaviour during invasion and occupation of the host colony. Several morphological adaptations such as bigger body parts and more curved sting shafts are observed in these wasps to aid their aggressive parasitic behaviour. Once they occupy a host's nest, V. infernalis are known to engage in mauling and chasing of host workers and forced trophallaxis. Female wasps will also force host workers to feed and take care of their brood.
