Metoecus paradoxus, also known as the wasp nest beetle and eyelash bug, is a species of Metoecus in the family Ripiphoridae. [1]
M. paradoxus measures approximately 10 mm in length. It has a dark head and body and paler, orange-coloured pointed elytra that do not completely cover the abdomen. It has feathery antennae. [2]
M. paradoxus is primarily a parasitoid of Vespula vulgaris (the common wasp). Adult females lay eggs in decaying wood in autumn, which hatch in spring or summer. The first instar triungulin clings to a V. vulgaris worker to be transported to the nest. Once at the nest, the larva parasitises a wasp larva – once the larva has closed the cell, the M. paradoxus larva consumes the host and pupates in its place. Adults emerge from late July to early October. The development from larva to adult takes less than one month. Adult beetles live for between 6 and 12 days and probably do not feed. [3]
Parasites employ various mechanisms, including chemical mimicry and chemical camouflage, to mimic the host colony's odor. When the M. paradoxus beetle penetrates the V. vulgaris host, it is vital that it avoids being detected. The same goes for all parasitic social insect species. These beetles seem to avoid being detected by mimicking the cuticular hydrocarbon profile of their host, the common wasp. A study found that M. paradoxus shares around 91.1% of compounds with V. vulgaris.[ citation needed ]
In 2020, American rapper Megan Thee Stallion created an Instagram post featuring a video of her and a female friend talking about a beetle with large antennae in Megan's house. Megan's friend asks what the bug is, and Megan responds with, "A bitch-eyelash bug," and the two laugh. Megan then says the bug's eyelashes are "on fleek" and says that "[It] just got [its] eyelashes done at the club." The bug then begins to fly, Megan and her friend scream, and the video stops. [4] A second recording shows comments of people reacting to it and identifying it as M. paradoxus as Megan's friend shows her images of it, to which Megan replies, "Bitch, that is her. Look at them damn lashes! That is crazy." [5] The first video has since gone viral and has become an internet meme.
However, the bug in the video looks more like a male Pterotus obscuripennis , of the firefly family. [6]
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites of other insects, such as bees, wasps, leafhoppers, silverfish, and cockroaches. Females of most species never emerge from the host after entering its body, finally dying inside it. The early-stage larvae do emerge because they must find an unoccupied living host, and the short-lived males must emerge to seek a receptive female in her host. They are believed to be most closely related to beetles, from which they diverged 300–350 million years ago, but do not appear in the fossil record until the mid-Cretaceous around 100 million years ago.
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host. They are found on all continents other than Europe and Antarctica.
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.
Elasmucha grisea, common name parent bug, is a species of shield bugs or stink bugs belonging to the family Acanthosomatidae. The term parent bugs includes also the other species of the genus Elasmucha and some species of the family Acanthosomatidae.
The varied carpet beetle is a 3 mm-long beetle belonging to the family Dermestidae, positioned in subgenus Nathrenus. They are a common species, often considered a pest of domestic houses and, particularly, natural history museums, where the larvae may damage natural fibers and can damage carpets, furniture, clothing, and insect collections. A. verbasci was also the first insect to be shown to have an annual behavioral rhythm and to date remains a classic example of circannual cycles in animals.
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.
Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae.
Meloe is a genus of blister beetles commonly referred to as oil beetles. The name derives from their defensive strategy: when threatened by collectors or predators they release oily droplets of hemolymph from their joints. This fluid is bright orange and contains cantharidin, a poisonous chemical compound. Wiping the chemical on skin can cause blistering and painful swelling of the skin. This defensive strategy is not exclusive to this genus; all meloids possess and exude cantharidin upon threat.
Clytus arietis, the wasp beetle, is a wasp-mimicking longhorn beetle species in the genus Clytus.
Bombylius major is a parasitic bee mimic fly. B. major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and are often mistaken for them.
Dasymutilla occidentalis is a species of parasitoid wasp that ranges from Connecticut to Kansas in the north and Florida to Texas in the south. Adults are mostly seen in the summer months.
Blastophaga psenes is a wasp species in the genus Blastophaga. It pollinates the common fig Ficus carica and the closely related Ficus palmata. Without a colony or nest, these wasps breed in figs, and the adults live for only a few days or weeks. They locate the fig they wish to pollinate through olfactory senses.
Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia. It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest. It is associated with citrus, but it attacks a wide range of crop plants, ornamental plants, and wild flora.
Belonogaster petiolata is a species of primitively eusocial wasp that dwells in southern Africa, in temperate or subhumid climate zones. This wasp species has a strong presence in South Africa and has also been seen in northern Johannesburg. Many colonies can be found in caves. The Sterkfontein Caves in South Africa, for example, contain large populations of B. petiolata.
Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.
Melittobia australica is a species of chalcid wasp from the family Eulophidae which is a gregarious ecto-parasitoid of acuealate Hymenoptera.
Meloe americanus is a type of blister beetle (Meloidae) found in North America. It is most relevant to the fields of agriculture and veterinary medicine. Adult beetles feed on different types of plants, which cause crop damage. They also release a fluid containing a chemical that is toxic, and at high concentrations lethal, to mammals. The first instar larvae are uniquely active and mobile, utilizing phoresy and parasitism to feed and mature through their developmental stages.
Macrosiagon limbata is a species of wedge-shaped beetle in the family Ripiphoridae. They are found across the Eastern United States, Southeastern Canada and Central America. It is likely that their range extends into South America but this currently remains unknown.
Mallophora ruficauda is a species of parasitic robber fly in the family Asilidae, endemic to South and Central America. Like other robber flies, M. ruficauda is known for its aggressive behavior and predation upon other insects, especially bees. M. ruficauda mimics a bumblebee to fool predators into thinking it has a painful sting and is not worth eating.
Campsomeriella thoracica is a species of scarab parasitoid wasp that has been recorded in the Middle East, Mediterranean, and Sub-Saharan Africa.
