Lucilia sericata, commonly known as the green bottle fly, is a species of blow fly found in many parts of the world. It is easily recognized by its shiny, metallic green coloration and is typically about 8 to 10 millimeters in length. These flies are often attracted to decaying organic matter, where they lay their eggs. The larvae of Lucilia sericata play a crucial role in the ecosystem by helping to decompose dead animals and organic waste. They are also used in medical settings for maggot therapy, where the larvae are applied to wounds to promote healing and prevent infection.
