Sarcophaga is a genus of flies commonly known as flesh flies. They are typically gray or black and are characterized by their striped thorax. These flies are often found in decaying organic matter, where they lay their eggs. The larvae, or maggots, feed on the decomposing material, playing a crucial role in the ecosystem by helping to break down dead animals. Flesh flies are also known for their unique reproductive behavior; they give birth to live larvae instead of laying eggs. This adaptation allows the larvae to begin feeding immediately, increasing their chances of survival. They are often associated with carrion and can be found in various habitats worldwide.
