Black Scavenger Fly or Ensign Fly is a common name of flies in the family Sepsidae. There are about 150 species of Black Scavenger Flies. Many species resemble ants having a waist and glossy black body and that's why, they are commonly known as Ant Flies. They are usually found around animals excrement or decaying plants, where they lay eggs and then their larvae live in that material. Being decomposers of animal excrement, they play an important biological role.
