Myriophora alexandrae is a parasitic insect from the genus Myriophora . Myriophora are flies that kill their definitive host, millipedes.
This is a "new world" parasite that has been found in the Southwestern part of the United States, and Central America specifically, Costa Rica
Myriophora are initially attracted to the chemical toxin released by their host that is used to keep predators away. However, this same toxin is what attracts the Myriophora. Specifically, the flies are more attracted when 2-methoxy-3-methyl-1,4-benzoquinone is combined with another chemical 2-methyl-1,4-benzoquinone. [2]
An adult female body length ranges form 1.54-1.93 mm. Each adult has one ovipositor located on the posterior end of the parasite that is a needle like shape. It has two wings and each wing ranges from 1.4-1.96mm in length. The top half of the parasite is brown and the bottom half is white. [3]
When an adult female Myriophora locates a millipede, it uses its ovipositor to penetrate the millipede in an unprotected areas (e.g. base of the antennae, between body segments, and the unprotected underbelly) of the millipede. An egg is delivered through the ovipositor and hatches inside of the millipede. Once the egg hatches, the maggot ingests the insides of the millipede a process that takes approximately five days. Once the millipede is fully consumed, all that will be left is the hind-gut and the exuvia. The Myriophora maggot then metamorphoses into an adult fly. [2]
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all zoogeographical regions and is especially diverse in South America.
The Calliphoridae are a family of insects in the order Diptera, with 1,200 known species. The maggot larvae, often used as fishing bait, are known as gentles. The family is known to be polyphyletic, but much remains disputed regarding proper treatment of the constituent taxa, some of which are occasionally accorded family status.
The apple maggot, also known as the railroad worm, is a species of fruit fly, and a pest of several types of fruits, mainly apples. This species evolved about 150 years ago through a sympatric shift from the native host hawthorn to the domesticated apple species Malus domestica in the northeastern United States. This fly is believed to have been accidentally spread to the western United States from the endemic eastern United States region through contaminated apples at multiple points throughout the 20th century. The apple maggot uses Batesian mimicry as a method of defense, with coloration resembling that of the forelegs and pedipalps of a jumping spider.
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan Megaselia scalaris. At 0.4 mm in length, the world's smallest fly is the phorid Euryplatea nanaknihali.
Braulidae, or bee louse, is a family of fly (Diptera) with seven species in two genera, Braula and Megabraula. Found in honey bee colonies, these most unusual wingless and small flies, are not a true bee parasite, and are barely recognizable as Diptera, as they have the superficial appearance of mites or lice.
Delia flies are members of the Anthomyiidae family within the superfamily Muscoidae. The identification of different species of Delia can be very difficult for non-specialists as the diagnostic characteristics used for immature and/or female specimens may be inconsistent between species. Past taxonomic keys were not as comprehensive in their identification of Delia specimens; they were either too reliant on genetic characteristics, focused solely on a specific life stage, or were focused only on certain species. However current taxonomic keys aim to be more thorough by not only including morphological diagnostics for males, females, and immature specimens of various species, but also their genetic make-up or molecular barcode.
Bactrocera dorsalis, previously known as Dacus dorsalis and commonly referred to as the oriental fruit fly, is a species of tephritid fruit fly that is endemic to Southeast Asia. It is one of the major pest species in the genus Bactrocera with a broad host range of cultivated and wild fruits. Male B. dorsalis respond strongly to methyl eugenol, which is used to monitor and estimate populations, as well as to annihilate males as a form of pest control. They are also important pollinators and visitors of wild orchids, Bulbophyllum cheiri and Bulbophyllum vinaceum in Southeast Asia, which lure the flies using methyl eugenol.
Haematobia irritans, the horn fly, is a small fly. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is of the genus Haematobia which is the European genus of bloodsucking flies. Haematobia irritans is a native of Europe but has been introduced to North America and is considered a potentially dangerous livestock pest.
Rhagoletis mendax is a species of tephritid fruit fly known by the common name blueberry maggot. The blueberry maggot is closely related to the apple maggot, a larger fruit fly in the same genus. It is a major pest of plant species in the Ericaceae family, such as blueberry, cranberry, and huckleberry. The larva is 5 to 8 mm long, apodous, and white with chewing mouthparts. Female adults are 4.75mm in length, males are slightly smaller. Both adults are mostly black in color with white stripes, orange-red eyes, and a single pair of clear wings with black banding. The adult female fly lays a single egg per blueberry, and when the larva hatches it consumes the fruit, usually finishing the entire berry in under 3 weeks and rendering it unmarketable. The larva then falls to the soil and pupates. Adult flies emerge, mate, and females oviposit when blueberry plants are producing fruit. Each female fly can lay 25 to 100 eggs in their lifetime.
The common toad fly, Lucilia silvarum, is a member of the fly family Calliphoridae. This fly was first discovered by Johann Wilhelm Meigen in 1826 and is found most notably in European and Western Countries.
Lucilia thatuna belongs to the family Calliphoridae, the species most commonly referred to as the blowflies, and the genus Lucilia. Along with several other species of Lucilia, L. thatuna is commonly referred to as a green bottle fly. L. thatuna is very scarce and not much is known about this particular fly. It has been noted to reside in mountainous regions of the northwestern United States.
Rhagoletis juglandis, also known as the walnut husk fly, is a species of tephritid or fruit fly in the family Tephritidae. It is closely related to the walnut husk maggot Rhagoletis suavis. This species of fly belongs to the R. suavis group, which has a natural history consistent with allopatric speciation. The flies belonging to this group are morphologically distinguishable.
Melaloncha is a genus of phorid flies commonly referred to as "bee-killing flies". They are found almost exclusively in the Neotropical region, although there is one record from extreme southern Texas, United States. They are small flies, usually about 2–3 millimetres (0.08–0.12 in) in length. No true fossils are known, although there are some specimens in Colombian copal, of unknown age.
Apocephalus borealis is a species of North American parasitoid phorid fly that attacks bumblebees, honey bees, and paper wasps. This parasitoid's genus Apocephalus is best known for the "decapitating flies" that attack a variety of ant species, though A. borealis attacks and alters the behavior of bees and wasps. These flies are colloquially known as zombie flies and the bees they infect are colloquially known as zombees. Association with honey bees has so far only been documented from California, South Dakota, Oregon, Washington, British Columbia, and Vermont.
Anastrepha suspensa, known as the Caribbean fruit fly, the Greater Antillean fruit fly, guava fruit fly, or the Caribfly, is a species of tephritid fruit fly. As the names suggest, these flies feed on and develop in a variety of fruits, primarily in the Caribbean. They mainly infest mature to overripe fruits. While thought to have originated in Cuba, the Caribbean fruit fly can now also be found in Florida, Hispaniola, and Puerto Rico.
Howardula is a genus of nematode that infests the larvae of mushroom-feeding flies, beetles, and other insects. Various Howardula species and strains infest mushroom-feeding Drosophila, including Howardula aoronymphium and Howardula neocosmis. Howardula husseyi can infest the mushroom phorid Megaselia halterata.
Apocephalus paraponerae is a species of fly in the family Phoridae discovered by Borgmeier in 1958. This species is a parasitoid of the giant tropical ant Paraponera clavata and uses both visual and chemical cues to locate its host. A. paraponerae can locate fighting or injured ants through host-produced alarm pheromones. Female flies are attracted to the ant to feed and oviposit, while males are attracted to feed and locate females for mating. There is some evidence that suggests that A. paraponerae is a cryptic species complex of at least four genetically distinct species.
Pseudacteon tricuspis is a parasitic phorid fly that decapitates its host, the imported Solenopsis invicta fire ant. There are over 70 described species within the Pseudacteon genus, which parasitize a variety of ant species. However, P. tricuspis is very specific to its host ant and will not attack other native ant species, making it a good biological control against the fire ant. P. tricuspis was also introduced into the United States for this purpose. Aside from the United States, P. tricuspis has also been found in South America, Europe, and Asia. Female P. tricuspis deposit their eggs directly into the fire ant host. Deposition into the ant host determines the sex of the egg, which grows within the host until adulthood, killing and decapitating the host in the process. Interestingly, P. tricuspis has a male-biased sex ratio, where the males are smaller than the females.
Myriophora is a genus of flies in the family Phoridae.
