Common flesh fly
Common flesh flies are 10 to 16 mm long. They are grey to black in colour with a fleck-like pattern. Their eyes are red. Like nearly all flesh flies (fam. Sarcophagidae), the females deposit complete, freshly hatched young larvae instead of laying eggs. Aside from this, their lifestyle is similar to that of the bluebottle.
It causes the same damage as the bluebottle.
