The black blow fly can be important in forensic investigations since these flies are attracted to decaying organic matter and will colonize a human corpse in a consistent time frame. The life cycle of the flies can be analyzed to narrow down a time of death. They are most often found in rural areas, particularly near sources of water.

Distinctive for its striking appearance during flight, locust blowfly is an adept aerial acrobat, capable of hovering and swift maneuvers thanks to its specialized wing structure. Feasting primarily on nectar from flowers, this species contributes to pollination, playing an understated role in maintaining the balance of ecosystems they inhabit. Their larvae, however, diverge sharply in dietary preferences, feeding on the decomposing matter of dead animals, which assists in nutrient recycling in their habitats.

Calliphora vomitoria is 1.02 - 1.5 cm long, almost twice the size of a housefly. The head and thorax are dull gray, the back of head has long yellow-orange setae and the abdomen is bright metallic blue with black markings. Its body and legs are covered with black bristle-like hair. It has short, clubbed antennae and 4 tarsi per leg. The eyes are red and the wings are transparent. The legs and antennae are black and pink. The chest is bright purple and has spikes to protect itself from other flies.

The blue blowfly is a species that is used in forensic investigations to determine the time of death of a human, based on the consistent timeframe when this insect arrives to colonize the body. The adults arrive two days after death, and the total life cycle of the blue blowfly lasts about 18 days.

Cochliomyia macellaria is a fly species from the family of bluebottles (Calliphoridae). The scientific name of the species was first validly published in 1775 by Fabricius.

Since the larvae of the common green bottle fly feed only on dead tissue, they are sometimes used for maggot therapy, where the larvae are introduced into a human wound to remove the dead tissue. The adults will feed on feces as well as pollen and nectar, making them important pollinator insects.

The bust and abdomen have a blue-green to emerald-green color. A copper glaze may develop in older animals. The big eyes are brown-red. The species reaches a body length of 11 mm and occurs in different environments from May to October. The adult flies feed on pollen and nectar. The larvae develop in bait and in wounds of sheep and other animals.
