Eggs hatch into larvae (maggots) in how many hours?

• A. 6-12 hours
• B. 48-72 hours
• C. 12-24 hours
• D. 1-2 hours

Answer: (C)

The timing being tested is how long after an egg is laid it takes to hatch into a larva. In forensic entomology, eggs typically hatch within roughly 12 to 24 hours under common environmental temperatures. This window reflects the normal embryo development time for many fly species before the first instar larva emerges. A shorter span like 6–12 hours is usually too fast for most eggs to complete embryogenesis, while a longer span such as 48–72 hours would be past hatching and into later larval development. At cooler temperatures, hatch can be slower but still tends to fall around a day, whereas warmer conditions can shorten the time but still generally fit the 12–24 hour range.
