Fly life cycle. Diagram and artworks showing the stages in the life cycle of a fly. The winged adult stage is at top centre. The female lays eggs (upper right) that are around 1.2 millimetres in length. These contain embryos and hatch into larvae around 3 millimetres long. Three sizes (instars) of larvae are shown here (across bottom). Once the fly larva (maggot) has reached a certain size (7 to 12 millimetres), it forms a pupal stage (upper left, 8 millimetres long). The adult fly (6 to 7 millimetres long) emerges from the pupa. The whole cycle can last between 10 days and two months depending on conditions.
