The Blow Fly is a common insect belonging to the family Calliphoridae. These flies are typically metallic blue or green and are often found near 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 waste. Blow flies are also known for their rapid life cycle, which can be completed in as little as two weeks under ideal conditions. They are important in forensic science, as the presence of Blow Fly larvae can help estimate the time of death in criminal investigations.
