Lucilia is a genus of flies commonly known as green bottle flies. They are part of the family Calliphoridae and are easily recognized by their shiny, metallic green coloration. These flies 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 helping to break down waste. These flies are also known for their association with forensic science, as their presence can help estimate the time of death in forensic investigations. Their life cycle is relatively short, making them useful indicators in various ecological studies.
