Calliphora vomitoria, commonly known as the bluebottle fly, is a species of blow fly found in many parts of the world. It is easily recognized by its shiny blue or green body and is often seen around decaying organic matter, where it lays its eggs. The larvae, or maggots, feed on decomposing material, playing a crucial role in the ecosystem by helping to break down waste. This fly is also known for its association with human health, as it can be a vector for various diseases. While it is not typically harmful to humans, its presence in food or living areas can be a concern, prompting the need for proper sanitation and waste management.
