Lucilia sericata, commonly known as the common green bottle fly, is distinguished by its metallic green color. It thrives in urban and rural areas worldwide, favoring warm climates. These flies play an essential role in decomposing organic matter and are used in forensic entomology to estimate time of death. They display unique larval behavior known as maggot therapy, beneficial in medical treatments for cleaning necrotic tissue.

Lucilia sericata, commonly known as the common green bottle fly, is native to the Palearctic region. Its geographical distribution includes Europe, Asia, and North Africa. It is widely introduced and now found globally, including North America, Australia, and New Zealand.

Lucilia sericata typically inhabits temperate and warm climates. It thrives in environments where there is decaying organic matter, including urban, suburban, and rural areas. The species is commonly found near garbage, carrion, and faecal matter, which provides breeding sites and food for larvae.

Lucilia sericata plays an important ecological role as a decomposer, helping to break down organic matter. It is also a pollinator and serves as a food source for various predators. The species is known for its role in forensic entomology, as its presence on carrion can help estimate post-mortem intervals. Additionally, it is used in maggot therapy for wound cleaning due to its larvae's ability to consume dead tissue without harming living tissue.
