flies on meat

Non-biting flies (or 'filth flies') are incredibly prolific and live in close habitation with humans (much to the annoyance of most humans). The life cycles of flies are complex, though each species shares the same developmental stages: an egg, larval (maggot) stage, pupa, and finally the adult. Adult flies possess antennae with special sensory cells that enable them to locate food and suitable breeding sites through the detection of compounds such as ammonia and carbon dioxide which are emitted from decomposiong organic materials such as faeces and carrion.
