Which of the following fly species are known to breed in animal carcasses?

Blow flies are well-known for their role in the decomposition process and are commonly associated with breeding in animal carcasses. These flies are often among the first insects to arrive at a dead animal, attracted by the scent of decay. They lay their eggs in the carcass, and the larvae (maggots) thrive on the organic material, contributing significantly to the breakdown of the carcass.

Blow flies belong to the family Calliphoridae, and their ability to detect and locate decaying matter from a distance makes them critical species in forensic entomology, where their presence can help estimate the time of death in criminal investigations.

In contrast, while house flies may also be found near carcasses, they are not as specialized in this habitat as blow flies. Fruit flies are mainly associated with decaying plant matter and are not typically found breeding in animal carcasses. Horse flies, on the other hand, are more commonly known for their blood-feeding behavior and do not breed in carcasses. Therefore, among the options provided, blow flies are the most accurately associated with breeding in animal carcasses.
