Blaesoxipha
Grasshopper Flesh Flies
Blaesoxipha is a genus of flesh flies (Sarcophagidae) with cosmopolitan distribution. Species in this genus are parasitoids, primarily attacking grasshoppers and related orthopterans. Some species have been documented as agents of myiasis in vertebrates. The genus includes notable species such as B. plinthopyga, which can cause myiasis, and B. redempta, a parasitoid of Stauroderus scalaris distributed across the Palearctic realm.
Calliphoridae
blow flies, blow-flies, carrion flies, bluebottles, greenbottles, cluster flies
Calliphoridae is a large family of Diptera containing approximately 1,900 described species with worldwide distribution. Adults are typically recognized by their metallic blue, green, or black coloration. The family exhibits diverse life histories including saprophagy, facultative parasitism, and obligatory myiasis. Larvae of most species develop in carrion and dung, making them ecologically important decomposers and forensically significant indicators of post-mortem intervals. Several species have substantial economic and medical importance: Lucilia cuprina causes flystrike in Australian sheep, Cochliomyia hominivorax was a major screwworm pest before eradication in North America, and Lucilia sericata is used in maggot debridement therapy for wound treatment.
Cephenemyia
deer botfly, deer nose bot, nasal bot fly
Cephenemyia is a genus of bot flies in the family Oestridae, commonly known as deer bot flies or nasal bot flies. These large, robust flies are specialized parasites of cervid ungulates (deer, elk, moose, caribou), with larvae developing in the nasal passages, pharynx, and throat of their hosts. The genus exhibits remarkable mimicry of bumblebees in appearance and behavior. Females are larviparous, depositing active first-instar larvae directly onto hosts. The genus has a Holarctic distribution, with multiple species in North America and Eurasia.
Cephenemyia apicata
nose bot fly
Cephenemyia apicata is a nose bot fly (family Oestridae) that parasitizes Columbian black-tailed deer (Odocoileus hemionus columbianus). First instar larvae develop in the deer's bronchi for 6–8 months before migrating to retropharyngeal pouches. Adult males aggregate at elevated stands of Castanopsis and Quercus in California, with activity occurring from April through July when air temperatures reach 20°C. Females exhibit a distinctive visible attack behavior, landing on or near deer and eliciting curiosity before larvipositing into nostrils.
Cephenemyia jellisoni
nose bot fly
A parasitic bot fly whose larvae develop in the nasal passages and pharyngeal recesses of deer. Adults are active during warm periods and exhibit specific mating aggregations on elevated vegetation. The species shows a covert attacking strategy when larvipositing, remaining undetected by hosts until the moment of larval deposition.
Cephenemyia pratti
nose bot fly
Cephenemyia pratti is a species of nose bot fly in the family Oestridae, described by Hunter in 1916. Like other members of the genus Cephenemyia, it is an obligate parasite of cervids (deer family). The species is poorly documented in scientific literature, with only six observations recorded on iNaturalist as of the knowledge cutoff.
Chironomus crassicaudatus
thick-tailed non-biting midge, thick-skinned midge
Chironomus crassicaudatus is a non-biting midge in the family Chironomidae, described by Malloch in 1915. The species is known from the eastern United States, ranging from Texas to New York. It has been documented in a rare case of human urogenital myiasis in Kolkata, India, where larvae were found in the urine of a patient living in unhygienic conditions with shared toilet facilities. As a member of the non-biting midges, adults lack functional mouthparts and do not feed on blood.
Chrysomya
Old World blow fly
Chrysomya is a genus of blow flies in the family Calliphoridae, native to the Old World. The genus is distinguished by metallic blue-green coloration, thick setae on the meron, and plumose arista. Several species have become forensically significant due to their predictable developmental rates and association with carrion, with some species recently expanding into North America.
Chrysomya megacephala
oriental latrine fly, oriental blue fly
Chrysomya megacephala is a warm-weather blowfly with metallic blue-green coloration, notable for its forensic importance in estimating post-mortem intervals due to its rapid colonization of corpses. The species exhibits two distinct forms: a normal forest-dwelling form restricted to South Pacific Islands, and a synanthropic derived form that has spread globally from Papua New Guinea and is closely associated with human environments. It serves as a significant public health concern through its role in causing accidental myiasis and mechanically transmitting pathogens to human food.
Chrysomya rufifacies
hairy maggot blow fly, hairy maggot blowfly
Chrysomya rufifacies is a blow fly native to Australasia and Southeast Asia that has become established across the Americas, Africa, and parts of Europe through human-mediated dispersal. It is one of the most forensically significant insects due to its highly predictable developmental timing and tendency to colonize human remains within minutes of death. The species exhibits facultative predation on other carrion-feeding larvae, which can alter postmortem succession patterns and confound time-of-death estimates. Adults are medium-sized with metallic blue-green coloration; larvae are distinguished by prominent fleshy tubercles that give the species its common name.
Cochliomyia
New World screwworm flies, screwworm flies
Cochliomyia is a genus of blowflies (family Calliphoridae) comprising four species: C. macellaria, C. hominivorax, C. aldrichi, and C. minima. The genus is commonly known as New World screwworm flies, distinguished from Old World screwworms. C. hominivorax, the primary screwworm, is an obligate parasite whose larvae feed on living tissue, causing severe myiasis in livestock, wildlife, and humans. C. macellaria, the secondary screwworm, feeds only on necrotic tissue and carrion. The primary screwworm has been eradicated from North America through the sterile insect technique, though it persists in parts of Central and South America.
Cochliomyia hominivorax
New World screwworm fly, New World screwworm, screwworm, screw-worm
Cochliomyia hominivorax, the New World screwworm fly, is an obligate parasitic blowfly whose larvae feed exclusively on living tissue of warm-blooded vertebrates. It is the only parasitic species in its genus; other Cochliomyia species are facultative parasites or carrion feeders. The species was eradicated from the United States, Central America, and much of the Caribbean through the sterile insect technique beginning in the 1950s, though it persists in tropical and subtropical South America and portions of the Caribbean. A 2016 outbreak in the Florida Keys was successfully eliminated, but detections in southern Mexico in 2024–2025 triggered renewed eradication efforts and trade restrictions.
Cochliomyia macellaria
secondary screwworm, secondary screwworm fly
Cochliomyia macellaria, the secondary screwworm, is a blow fly in the family Calliphoridae distributed throughout the Americas from southern Canada to Patagonia. The species is a specialist carrion colonizer whose larvae feed on necrotic tissue, distinguishing it from the primary screwworm (C. hominivorax) which attacks living tissue. Adults exhibit metallic blue-green coloration with orange-red eyes and head. The species holds significant forensic importance for postmortem interval estimation and has medical-veterinary relevance as a cause of secondary myiasis in livestock and humans.

As a member of the genus Cuterebra, it is an obligate parasite of mammals with larvae that develop subcutaneously in host tissue. The species is one of 34 recognized North American Cuterebra species. Very little specific information has been published about this particular species.
Cuterebra cuniculi
rabbit bot fly
Cuterebra cuniculi is a New World skin bot fly endemic to Georgia and Florida. Its larvae are obligate parasites of the eastern cottontail (Sylvilagus floridanus) and marsh rabbit (Sylvilagus palustris), developing subcutaneously in warbles. Adults are short-lived, lack functional mouthparts, and do not feed.
Cuterebra emasculator
Squirrel Bot Fly
Cuterebra emasculator is a New World bot fly and obligate internal parasite of tree squirrels and chipmunks in eastern North America. First described by Asa Fitch in 1856, its larvae develop subcutaneously in hosts, creating characteristic swellings called warbles. The species name originated from a false belief that larvae consumed host testicles; research has shown this is not the case and parasitism does not reduce host fertility. Adults are rarely encountered, lack functional mouthparts, and live only a few days focused solely on reproduction.
Cuterebra fontinella
mouse bot fly
Cuterebra fontinella, commonly known as the mouse bot fly, is a New World oestrid fly that parasitizes small mammals, particularly the white-footed mouse (Peromyscus leucopus). Adults are short-lived, non-feeding, and resemble bumble bees in appearance. Females lay eggs on vegetation near host burrows; larvae enter through natural orifices or wounds, migrate internally, and develop subcutaneous warbles typically located in the inguinal region. The species exhibits bimodal seasonal activity with summer and autumn population peaks. Though primarily a rodent parasite, rare human cases of myiasis have been documented.
Cuterebra fontinella fontinella
mouse bot fly, white-footed mouse bot fly
Cuterebra fontinella fontinella is a subspecies of New World bot fly (family Oestridae) that parasitizes small mammals, primarily white-footed mice (Peromyscus leucopus). The adult flies are large, bumble bee-sized, and lack functional mouthparts, living only briefly to reproduce. Females lay eggs near host burrow entrances; larvae hatch in response to host body heat, enter through orifices or wounds, and develop subcutaneously for approximately one month before exiting to pupate in soil. Despite forming conspicuous warbles that can reach 5% of host body weight, infections appear to have minimal negative impact on host survival and may even correlate with increased longevity in some populations.
Cuterebra fontinella grisea
Cuterebra fontinella grisea is a subspecies of New World skin bot fly (family Oestridae) that parasitizes small mammals, particularly white-footed mice (Peromyscus leucopus). The larvae develop subcutaneously in the host, forming large warbles that can reach 5% of the host's body weight. Despite the conspicuous nature of these parasitic infections, studies indicate that infected mice may actually live longer than non-infected individuals, suggesting a relatively benign host-parasite relationship attributed to long evolutionary co-adaptation. Adults are short-lived, lack functional mouthparts, and are rarely encountered in the field.
Cuterebra lepusculi
cottontail rabbit botfly
Cuterebra lepusculi is a New World skin bot fly (family Oestridae) that parasitizes cottontail rabbits (Sylvilagus spp.). Adults are short-lived, lack functional mouthparts, and do not feed. Females deposit eggs near rabbit burrow entrances; larvae hatch upon detecting host body heat, enter through natural orifices or wounds, and develop in subcutaneous warbles for approximately one month before exiting to pupate in soil.
Cuterebra polita
Cuterebra polita is a New World skin bot fly whose larvae are obligate parasites of rodents. Adults are non-feeding and short-lived, lacking functional mouthparts. Larvae develop in subcutaneous warbles on host rodents, feeding on host tissues and fluids. The species has been documented in four rodent hosts in Florida: white-footed mouse, cotton mouse, eastern woodrat, and cotton rat.
Cuterebra tenebriformis
Cynomya
dog-fly
Cynomya is a genus of blow flies (family Calliphoridae) commonly known as 'dog-flies' from the Ancient Greek κυνόμυια. Species in this genus are large, conspicuous flies of forensic interest, primarily distributed across the Palaearctic Region with some overlap in Alaska and the Russian Far East. The genus includes species such as C. mortuorum and C. cadaverina, which are associated with carrion and occasionally recorded as agents of myiasis. Unlike many calliphorids, Cynomya species are not strongly synanthropic and are rarely abundant in nature.
Eristalis
Drone Flies, Droneflies
Eristalis is a large genus of hoverflies (family Syrphidae) comprising approximately 99 species. Adults are commonly called drone flies due to their resemblance to honeybee drones, a form of Batesian mimicry that provides protection from predators. The larvae, known as rat-tailed maggots, are aquatic and possess an extendable breathing siphon that allows them to inhabit oxygen-depleted environments such as stagnant water, sewage, and decomposing organic matter. Adults are important generalist pollinators, with some species proposed as managed alternatives to honey bees for agricultural pollination.
Eristalis tenax
Common Drone Fly, Drone Fly, Rat-tailed Maggot
Eristalis tenax is a cosmopolitan hoverfly (Syrphidae) and the most widely distributed syrphid species globally, occurring on every continent except Antarctica. Adults are striking mimics of honey bees, exhibiting Batesian mimicry that provides protection from predators. The larval stage, known as the rat-tailed maggot, is aquatic and inhabits polluted water containing organic matter, using an elongated posterior siphon for respiration. Adults are important generalist pollinators, particularly of Asteraceae flowers. The species exhibits strong territorial behavior in males and has been documented to cause rare cases of accidental myiasis in humans.
Gasterophilus intestinalis
Horse Bot Fly, Horse Botfly
A parasitic bot fly found worldwide that infests the gastrointestinal tract of equids. Adults are bumblebee mimics active in summer, lacking functional mouthparts and living only a few weeks. Females cement eggs to horse hairs; larvae develop in the mouth and stomach for 8–10 months before exiting in feces to pupate. Infestations rarely cause clinical disease but adults are a nuisance to horses.
Hypoderma
Warble Flies, Heel Flies, Bomb Flies, Gadflies
Hypoderma is a genus of large parasitic flies in the family Oestridae, commonly known as warble flies. Adults are non-feeding and live only to reproduce. Females deposit eggs on the legs and flanks of cattle and other ungulates; first-instar larvae penetrate the skin and migrate through the host's body, typically to the gullet or spinal canal, before settling in subcutaneous tissues of the back to develop. The larvae create characteristic swellings (warbles) visible on the host's hide. Two economically important species are H. bovis (ox warble fly) and H. lineatum (cattle warble fly), which cause significant damage to cattle hides and reduce animal welfare.
Hypoderma lineatum
Common Cattle Grub, Ox Warble Fly
Hypoderma lineatum is a parasitic warble fly in the family Oestridae, commonly known as the common cattle grub. Adults emerge from puparia in early May, approximately one month before the related H. bovis. Females oviposit on cattle during sunny, calm weather from late May through early September, showing a preference for open areas and avoiding water and shade. First-instar larvae penetrate the host's skin and migrate to the gullet, where they develop for an average of 42.5 days before moving to subcutaneous tissues of the back. The species causes significant economic damage to cattle through hide degradation, reduced milk yield, and irritation during adult oviposition activity. Unlike H. bovis, H. lineatum does not terrify cattle during oviposition; animals typically show little uneasiness.
Hypoderma tarandi
Reindeer Warble Fly, Reindeer Botfly, Caribou Bot Fly
Hypoderma tarandi is a parasitic warble fly (Diptera: Oestridae) that infests reindeer and caribou across Arctic and subarctic regions. Adult females lay eggs on host hair shafts; larvae penetrate the skin and develop in subcutaneous tissues, creating warble lesions. The species has exceptionally strong flight capacity in females, with maximum lifetime flight distances estimated at 600–900 km, an adaptation linked to the migratory behavior of its host. Adults do not feed; they rely entirely on fat reserves accumulated during larval development. The species causes economic damage to hides, meat, and milk production in domesticated herds and has been documented causing ophthalmomyiasis in humans.
Hypodermatinae
warble flies
Hypodermatinae is a subfamily of bot flies (Oestridae) containing nine genera of large parasitic flies commonly called warble flies. The larvae develop as subcutaneous parasites in mammals, particularly bovines, causing economically significant damage to livestock. Adult flies are non-feeding and short-lived.

Oestrus is a genus of bot flies in the family Oestridae, parasitic on mammals. The best-known species, Oestrus ovis, commonly called the sheep bot fly, deposits larvae in the nasal cavities of sheep and goats, where they develop and cause respiratory distress. Adults are non-feeding and have reduced mouthparts. The genus has a Holarctic distribution, with records from northern Europe and other temperate regions.
Oestrus ovis
sheep bot fly, sheep nostril fly
Oestrus ovis is an obligate parasitic fly (Diptera: Oestridae) that develops exclusively within the nasal and sinus cavities of sheep and related ungulates. Females are larviparous, depositing live first-instar larvae directly into host nostrils during flight. Larvae develop through three instars within the host before exiting to pupate in soil. The species causes oestrosis, a condition marked by nasal discharge, respiratory distress, and reduced productivity in livestock. Human infestations, though uncommon, have been documented worldwide.
Paramacronychiinae
Paramacronychiinae is a subfamily of flesh flies within the family Sarcophagidae. The subfamily contains 23 genera and at least 32 species in China alone. Members include necrophagous species and some that cause myiasis in mammals. The group has been studied for forensic entomology applications due to carrion associations.
Piophila
cheese flies, wine flies
Piophila is a genus of small dipteran flies in the family Piophilidae, comprising two species: Piophila casei (the cheese fly or ham skipper) and Piophila megastigmata. Both species are carrion feeders with forensic importance, and P. casei is a significant pest of cured meat and cheese products. The genus occurs in the Palearctic and has been introduced to other regions.
Piophilidae
cheese skipper flies, skipper flies, cheese flies, ham skippers, bacon flies
Piophilidae are a family of small Diptera commonly known as cheese skipper or skipper flies. Most species are scavengers specialized on animal products, carrion, and fungi.
