Blowflies are a common sight during summer months, and different parts of the world have different names for these insects. In North America they may be called bluebottles or greenbottles, while in the UK they are referred to as carrion flies. Other synonyms for blowflies include flesh flies, which are known for laying their eggs on decaying flesh, and hoverflies, which resemble bees or wasps but feed on nectar. Blowflies can also be mistaken for houseflies due to their similar appearance, but blowflies tend to be larger and more iridescent in color. No matter what they are called, blowflies play an important role in nature by helping to break down and recycle organic matter.
