These metallic green blow flies can be found throughout Canada and the United States, and around the world. They are active on bright sunny days near houses and can often be seen sunning themselves on walls or sidewalks. They are also often seen around (and sipping on) dog feces. Adults will sip both plant and animal juices. Females sometimes lay eggs on open wounds and are among the first insects to arrive at a carcass. Larvae typically develop in rotting meat and pupate in soil. While a Green Bottle Fly’s foods of choice may seem disgusting, they are cleaning up the “waste” left behind by plants and animals, keeping ecosystems not only tidy, but healthy.
