Volucella pellucens, the pellucid fly, is a hoverfly. [1]
This species occurs in much of Europe, and across the Palearctic to Japan. [2] The adult V. pellucens is usually found in woodlands and wooded hedgerows, but will enter gardens. [3]
Volucella pellucens is about 13–17 mm in length, with a wing length about 10–15.5 mm. [4] [5]
This hoverfly has a broad, mainly black body, but the front part of the abdomen has a broad, yellow band, giving it the appearance of a bee or wasp. The two wings are transparent, as with most flies, but the leading edge is amber, with a brown patch on each wing. [5]
The mimicry of bees or wasps in shape and colouration is shown by other hoverflies, which is thought to protect against falling prey to birds and other insectivores that avoid eating true wasps because of their stings. However, the difference between hoverflies and wasps or bees is hoverflies have two wings, and the Hymenoptera species have four.
Adults live on nectar and pollen, as with most hoverflies, and visits a large range of flowers from May to October, [4] [3] [5] showing a distinct preference for white flowers, such as Sambucus, Cornus, Ligustrum , Rubus idaeus , and bramble and Apiaceae, but they also feed on Asteraceae, Valeriana officinalis , Succisa pratensis , Chamerion angustifolium , and Urtica dioica . [3] [4] It typically flies at head height.
The female enters the underground paper nests of the common wasp, Vespula vulgaris , or the German wasp, V. germanica, and lays her eggs. Despite the conspicuous nature of the intruder, the hosts do not appear to register her presence as she makes her way into the otherwise well-guarded nest entrance. The V. pellucens larvae then feed on the hosts' young and dead adults. [6]
When the eggs hatch, the larvae drop to the bottom of the nest chamber, where they feed as scavengers on debris. [5] This may include dead wasp grubs and adults, remains of food brought into the nest by the wasps, and other insects living there. Mature larvae are sometimes on the combs and have been recorded feeding on dead or moribund wasp larvae and pupae that were left in the combs when the nest was abandoned by the wasps in the autumn. Fully grown larvae leave the nest and pupate in the soil below. If the host nest is in the roof or walls of a house, then the larvae may end up crawling about in the dwelling space.
Adult hoverflies emerge the following year from about mid-May to June.
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.
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.
The Bombyliidae are a family of flies, commonly known as bee flies. Adults generally feed on nectar and pollen, some being important pollinators. Larvae are mostly parasitoids of other insects.
The European hornet is the largest eusocial wasp native to Europe. It is also the only true hornet found in North America, having been introduced to the United States and Canada from Europe as early as 1840. Vespines, such as V. crabro, are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought.
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.
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.
Volucella bombylans is a large species of hoverfly belonging to the family Syrphidae.
Volucella inanis is a species of hoverfly belonging to the family Syrphidae.
Eristalinae are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, Eristalis tenax.
Volucella is a genus of large, broad-bodied, dramatic hover-flies. They have distinctive plumose aristae and the face is extended downward. They are strongly migratory and males are often territorial. Adults feed on nectar of flowers and are often seen sunning on leaves. The larvae of most species live in nests of bumblebees and social wasps, where they are detritivores and larval predators.
Volucella zonaria, the hornet mimic hoverfly, is a species of hoverfly. These flies are capable of buzz pollination.
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 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.
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 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.
Mallophora bomboides, also known as the Florida bee killer, is a predaceous species of robber fly of the family Asilidae that feeds primarily on bumblebees. M. bomboides is a noteworthy instance of Batesian mimicry given its close resemblance to its prey, the bumblebee. These bees are typically found in the Eastern and Southern regions of the United States like South Carolina and Florida.
