Casu martzu, sometimes spelled casu marzu, and also called casu modde, casu cundídu and casu fràzigu in Sardinian, is a traditional Sardinian sheep milk cheese that contains live insect larvae (maggots).
The Piophilidae are a family of "true flies", in the order Diptera. The so-called cheese flies are the best-known members, but most species of the Piophilidae are scavengers in animal products, carrion, and fungi. They may accordingly be important in forensic entomology and medical entomology. For a fly maggot, the larvae of many species have an unusually well-developed ability to leap when alarmed or when abandoning their larval food to pupate; they accordingly may be known as cheese skippers or other kinds of skippers according to their food source.
Forensic entomology is an science study of colonization of a dead body by arthropods. This includes the study of insect types commonly associated with cadavers, their respective life cycles, their ecological presences in a given environment, as well as the changes in insect assemblage with the progression of decomposition. Insect succession patterns are identified based on the time a given species of insect spends in a given developmental stage, and how many generations have been produced since the insects introduction to a given food source. Insect development alongside environmental data such as temperature and vapor density, can be used to estimate the time since death, due to the fact that flying insects are attracted to a body immediately after death. The identification of postmortem interval to aid in death investigations is the primary scope of this scientific field. However, forensic entomology is not limited to homicides, it has also been used in cases of neglect and abuse, in toxicology contexts to detect the presence of drugs, and in dry shelf food contamination incidents. Equally, insect assemblages present on a body, can be used to approximate a given location, as certain insects may be unique to certain areas. Therefore, forensic entomology can be divided into three subfields: urban, stored-product and medico-legal/medico-criminal entomology.
Flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", and πτερόν pteron "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others, although only about 125,000 species have been described.
Pecorino is an Italian hard cheese produced from sheep's milk. The name pecorino derives from pecora, which means 'sheep' in Italian.
The apple maggot, also known as the railroad worm, is a species of fruit fly, and a pest of several types of fruits, especially 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.
Myiasis, also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae (maggots) that grow inside the host while feeding on its tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies as vector agents for their parasitic larvae.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
Eurytides marcellus, the zebra swallowtail, is a swallowtail butterfly native to the eastern United States and south-eastern Canada. It is the state butterfly of Tennessee. Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees. The green or black caterpillars feed on the leaves of various pawpaw species, while the adults feed on flower nectar and minerals from damp soil.
Pecorino sardo is a firm cheese from the Italian island of Sardinia, made from sheep's milk, specifically from the milk of the local Sardinian breed. It was awarded denominazione d'origine status in 1991 and granted protected designation of origin protection in 1996, the year in which this European Union certification scheme was introduced.
The olive fruit fly is a species of fruit fly which belongs to the subfamily Dacinae. It is a phytophagous species whose larvae feed on the fruit of olive trees, hence the common name. It is considered a serious pest in the cultivation of olives.
Tyrophagus casei, the cheese mite, is a species of mite which is inoculated into Milbenkäse and Altenburger Ziegenkäse cheese during their production. It is 0.45–0.70 millimetres (0.018–0.028 in) long, and feeds on cheese, corn, flour, old honeycombs, bird collections, and smoked meats.
Epargyreus clarus, the silver-spotted skipper, is a butterfly of the family Hesperiidae. It is claimed to be the most recognized skipper in North America. E. clarus occurs in fields, gardens, and at forest edges and ranges from southern Canada throughout most of the United States to northern Mexico, but is absent in the Great Basin and western Texas.
Fannia scalaris, also known as the latrine fly, is a fly species in the Fanniidae family. This species is smaller and more slender than the house fly, Musca domestica, and is similar in appearance to the lesser house fly, Fannia canicularis. The life cycle of this species can be as long as one month. These flies are globally distributed in urban areas as they are drawn to unsanitary environments. F. scalaris is a major cause of myiasis, the infestation of a body cavity by fly maggots. The adults infest bodies that have decomposed, making the species an important part of forensic entomology. The larvae of this fly have adapted protuberances, or feathered appendages, that allow them to survive in such a moist environment. Entomologists continue to research the effects that F. scalaris may have medically, forensically, and on the environment around them.
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.
Cheese mites are mites that are used to produce such cheeses as Milbenkäse, Cantal and Mimolette. The action of the living mites on the surface of these cheeses contributes to the flavor and gives them a distinctive appearance. A 2010 scanning electron microscope study found that Milbenkäse cheese was produced using Tyrophagus casei mites, while Mimolette cheese used Acarus siro mites. Mimolette cheese, in particular, has live cheese mites in its rind which is thought to contribute to the cheese's distinct rind texture.
Eating live animals is the practice of humans eating animals that are still alive. It is a traditional practice in many East Asian food cultures. Animals may also be eaten alive for shock value. Eating live animals, or parts of live animals, may be unlawful in certain jurisdictions under animal cruelty laws. Religious prohibitions on the eating of live animals by humans are also present in various world religions.
Necrobia violacea is a species of beetle in family Cleridae. Cleridae beetles are a predaceous beetle found within forest and woodland environments, and can be associated with stored food products as both pests and predators of other insects.
Cuterebra fontinella, the mouse bot fly, is a species of New World skin bot fly in the family Oestridae. C. fontinella is typically around 1 cm (0.39 in) in length with a black and yellow color pattern. C. fontinella develops by parasitizing nutrients from its host, typically the white-footed mouse. C. fontinella has even been known to parasitize humans in rare cases. Individuals parasitized by C. fontinella will develop a large bump on the skin that is indicative of parasitization.
Prochyliza xanthostoma, the waltzing fly, is a species of carrion-feeding cheese skipper, insects in the family Piophilidae and the order Diptera. P. xanthostoma is a member of the genus Prochyliza, which contains eleven species. The adult flies are found through North America and are brown-bodied, with orange and black coloring. Mating occurs on animal carcasses and male perform mating rituals; females engage in ejaculate feeding. The waltzing fly is known for its exaggerated sexual dimorphism and has thus become a prominent model for sexual dimorphism and larval behavior. These organisms are known as cheese skippers because when startled, the larvae can leap several inches into the air. P. xanthostoma is an important model organism for sexual selection, larval behavior, and adult reproductive success and survivability.
