Chrysomya marginalis, the regal blowfly, also referred to as the regal bluebottle or the bordered blowfly is an uncommon and relatively large species of fly that was described by Weidemann in 1830. [1] It is found in Africa to the south of the Sahara, [2] and is also found in various Middle-Eastern countries. [3]

Description

The regal blowfly is a large fly, whose body reaches a length of 18 mm. The body of the fly is cylindrical in shape and robust indeed. It is highly iridescent, reflecting light in a rich blue, a greenish-cyan, or a blueish-violet depending on the angle of which the creature is observed. The abdomen is divided into a few segments, marked with darkened bands with relative thickness. [4] It is short and compacted, almost cubic and geometrical. The thorax of the fly is shield-like and broad, split into three distinctive segments, and like the abdomen highlighted with darkened bands to mark said segments. The head of the fly is pale yellow bearing large, red, and faceted compound eyes. The male’s compound eyes are holoptic. Three ocelli are arranged in a triangular formation atop the fly’s head. Perhaps the most remarkable feature of the fly is its pair of wings. They are windowlike and hyaline, and possessing a darkened anterior wing margin which is the main defining feature used to identify the species, as it has been often confused with a similar species, Chrysomya megacephala .[ citation needed ]

The Calliphoridae are a family of insects in the order Diptera, with almost 1,900 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.

<i>Chrysomya putoria</i> Species of fly

Chrysomya putoria, also known as the tropical African latrine blowfly, is a fly species belonging to the blowfly family, Calliphoridae.C. putoria is native to Africa and has recently spread to the Americas. These flies pose significant health risks, especially due to their close association with human settlements. Adult flies can carry pathogens, while larvae may cause myiasis by growing and feeding on the flesh of domestic animals and humans. Other myiasis-causing flies in the same genus are C. bezziana and C. megacephala. C. putoria and other flies that feed on decomposing tissue are used as important tools in forensic entomology to establish the post-mortem interval, or the time elapsed since death.

<i>Cynomya mortuorum</i> Species of fly

Cynomya mortuorum belongs to the order Diptera, sometimes referred to as "true flies". In English, the only common name occasionally used is "fly of the dead". It has a bluish-green appearance, similar to other Calliphoridae and is found in multiple geographic locations with a preference for colder regions. Belonging to the family Calliphoridae, it has been shown to have forensically relevant implications due to its appearance on carrion. Current research is being done to determine C. mortuorum's level of importance and usage within forensic entomology.

<i>Calliphora vomitoria</i> Species of fly

Calliphora vomitoria, known as the blue bottle fly, orange-bearded blue bottle, or bottlebee is a species of blow fly, a species in the family Calliphoridae. Calliphora vomitoria is the type species of the genus Calliphora. It is common throughout many continents including Europe, Americas, and Africa. They are fairly large flies, nearly twice the size of the housefly, with a metallic blue abdomen and long orange setae on the gena.

<i>Chrysomya</i> Genus of flies

Chrysomya is an Old World blow fly genus of the family Calliphoridae. The genus Chrysomya contains a number of species including Chrysomya rufifacies and Chrysomya megacephala. The term “Old World blow fly” is a derivative of both the associated family, Calliphoridae, and the belief that the genus Chrysomya originated in Asia and migrated to North America only relatively recently. Chrysomya’s primary importance to the field of medico-criminal forensic entomology is due to the genus’ reliable life cycle, allowing investigators to accurately develop a postmortem interval. Chrysomya adults are typically metallic colored with thick setae on the meron and plumose arista. The name comes from the word chrysos, meaning “golden” in reference to the metallic sheen of the genus’ species, and -mya, a derivation from the word myia, meaning “fly”.

<i>Chrysomya rufifacies</i> Species of fly

Chrysomya rufifacies is a species belonging to the blow fly family, Calliphoridae, and is most significant in the field of forensic entomology due to its use in establishing or altering post mortem intervals. The common name for the species is the hairy maggot blow fly, and it belongs to the genus Chrysomya, which is commonly referred to as the Old World screwworms. This genus includes other species such as Chrysomya putoria and Chrysomya bezziana, which are agents of myiasis. C. rufifacies prefers very warm weather and has a relatively short lifecycle. It is widely distributed geographically and prefers to colonize large carcasses over small ones. The species commonly has a greenish metallic appearance and is important medically, economically, and forensically.

<i>Lucilia illustris</i> Species of insect

Lucilia illustris is a member of the fly family Calliphoridae, commonly known as a blow fly. Along with several other species, L. illustris is commonly referred to as a green bottle fly. Lucilia illustris is typically 6–9 mm in length and has a metallic blue-green thorax. The larvae develop in three instars, each with unique developmental properties. The adult fly typically will feed on flowers, but the females need some sort of carrion protein in order to breed and lay eggs.

<i>Calliphora vicina</i> Species of insect

Calliphora vicina is a member of the family Calliphoridae, which includes blow flies and bottle flies. These flies are important in the field of forensic entomology, being used to estimate the time of a person's death when a corpse is found and then examined. C. vicina is currently one of the most entomologically important fly species for this purpose because it arrives at and colonizes a body following death in consistent timeframes.

<i>Chrysomya megacephala</i> Species of fly

Chrysomya megacephala, more commonly known as the oriental latrine fly or oriental blue fly, is a member of the family Calliphoridae (blowflies). It is a warm-weather fly with a greenish-blue metallic box-like body. The fly infests corpses soon after death, making it important to forensic science. This fly is implicated in some public health issues; it can be the cause of myiasis, and also infects fish and livestock.

Compsomyiops callipes, previously known as Paraluclia wheeleri, is a member of the blowfly family Calliphoridae. It is a warm weather fly that can be found in southwestern parts of the United States and parts of South America. This species can be identified by its chaetotaxy, metallic blue color, club-shaped palp, and brown calypters.

<i>Lucilia mexicana</i> Species of insect

Lucilia mexicana is a species of blow fly of the family Calliphoridae, one of many species known as a green bottle fly. Its habitat range extends from southwestern North America to Brazil. L. mexicana is typically 6–9 mm in length with metallic blue-green coloring. This species is very similar in appearance to L. coeruleiviridis, the primary difference being that L. mexicana has two or more complete rows of post-ocular setae. L. mexicana has the potential to be forensically important in the stored-products and medicocriminal fields, but more research is needed for the fly to be used as evidence in criminal investigations.

<i>Calliphora livida</i> Species of fly

Calliphora livida is a member of the family Calliphoridae, the blow flies. This large family includes the genus Calliphora, the "blue bottle flies". This genus is important in the field of forensic entomology because of its value in post-mortem interval estimation.

<i>Lucilia coeruleiviridis</i> Species of fly

Lucilia coeruleiviridis, formerly Phaenecia coeruleiviridis, is commonly known as a green bottle fly, because of its metallic blue-green thorax and abdomen. L. coeruleiviridis was first discovered by French entomologist Pierre-Justin-Marie Macquart in 1855. It belongs to the family Calliphoridae and is one of many forensically important Diptera, as it is often found on decaying substances. L. coeruleiviridis is one of the most ubiquitous blow fly species in the southeastern United States, particularly in the spring and fall months.

<i>Protophormia terraenovae</i> Species of fly

Protophormia terraenovae is commonly called northern blowfly, blue-bottle fly or blue-assed fly. It is distinguished by its deep blue coloration and large size and is an important species throughout the Northern Hemisphere. This fly is notable for its economic effect as a myiasis pest of livestock and its antibiotic benefits in maggot therapy. Also of interest is P. terraenovae’s importance in forensic investigations: because of their temperature-dependent development and their prominent presence on corpses, the larvae of this species are useful in minimum post-mortem interval (mPMI) determination.

Calliphora loewi is part of the family Calliphoridae, bottle flies and blowflies, and in the genus Calliphora, blue bottle flies. The genus can be deceiving since C. loewi is not blue. Though this species is rare, it can play an important part in forensic entomology, spreading disease, and decomposing carrion. The life cycle of C. loewi is similar to the life cycle of the genus Calliphora. Since this species is rare there has not been very much research done with this species.

<i>Calliphora stygia</i> Species of fly

Calliphora stygia, commonly known as the brown blowfly, or rango tumaro in Māori, is a species of blow-fly that is found in Australia and New Zealand. The brown blowfly has a grey thorax and yellow-brown abdomen.

<i>Calliphora quadrimaculata</i> Species of fly

Calliphora quadrimaculata, commonly known as the New Zealand blue blowfly and by its Māori name rango pango, is an insect in the genus Calliphora of family Calliphoridae in the order Diptera. This particular blowfly is found throughout New Zealand as well as on Chatham, Auckland, Stewart and Campbell Islands that surround New Zealand. Generally blowfly maggots in New Zealand have to feed on animal tissue or faeces to develop into adult blowflies. However the New Zealand blue blowfly larvae can survive on decaying leaves of snow tussock in alpine regions and reach adult maturity without feeding on any animal tissue.
