Calliphora is a genus of flies commonly known as blowflies. They are typically characterized by their metallic blue or green coloration and are often found in decaying organic matter, where they lay their eggs. The larvae, or maggots, feed on decomposing material, playing a crucial role in the ecosystem by aiding in decomposition. These flies are also important in forensic science, as their presence can help estimate the time of death in criminal investigations. Calliphora species are widespread and can be found in various habitats around the world, making them significant both ecologically and scientifically.
