Green, blue and black bottle flies, along with carrion flies, dung flies, cluster flies and over 1,100 genera in the Calliphoridae species make up the vast family of blow flies. With green, blue and black shiny, metallic bodies, bottle flies are slightly larger than true houseflies and make loud buzzing noises in flight.
Common type of blow fly
Found in almost every part of the world, bottle flies are more concentrated in the Pacific region, particularly California and Australia. As some of the most common members of the blow fly family, bottle flies are drawn to recently deceased animal and human carcasses, ideal breeding grounds for blow fly eggs that need a lot of protein to develop into adults.
Forensic entomology aids crime investigators
Valuable to forensic investigation, bottle flies, capable of detecting dead animal matter from a mile away are generally the first insects to make contact with deceased animals and humans. Bottle fly larvae develop rapidly in a corpse and due to the reliability of larval development in bottle flies, forensic entomologists can determine the time of death of victims where other methods fail.
Bottle fly larvae used in healing
Sterilized bottle fly larvae, or maggots, are sometimes used to heal wounds, consuming necrotic or dead tissue and leaving healthy tissue intact. On the negative side, some bottle flies infest live tissue, causing a deadly condition known as myiasis. Bottle flies can also act as pollinators for strong odorous plants, such as paw paws and goldenrod.
