Flesh flies, belonging to the family Sarcophagidae, are large, robust insects commonly found in decaying organic matter. They are known for their gray or black coloration and distinctive striped appearance. Unlike house flies, flesh flies give birth to live larvae, which are often found in carrion or wounds of animals. These flies play a crucial role in the ecosystem by aiding in decomposition. Their larvae, known as maggots, consume dead tissue, helping to recycle nutrients back into the environment. Flesh flies are also studied in forensic science, as their presence can help determine the time of death in crime scene investigations.
