Stable flies have the same life cycle as house flies, but develop slightly slower.
At summer temperatures in temperate areas, the eggs hatch in 1–2 days and larval development requires 6–8 days.
The pupal stage lasts 6–8 days.
The entire life cycle (egg to adult) requires 13–18 days at temperatures of 24–30°C (75–85°F).
The preoviposition period (during which bloodmeals are needed) is about 6–8 days.
Like the house fly, the development of the stable fly is slowed at low temperatures and can require several weeks. For example, development from egg to adult at 10°C (50°F) requires 3–5 months.
