- Eggs are deposited at the edges of wounds, in groups of 150-500
eggs. (B24)
- Eggs hatch in 10-12 hours. (B24)
- The second stage larvae invade living tissue and the third stage
larvae are buried in tissue with only the posterior end of the
maggot protruding. (B455.w7)

days after hatching, to pupate on the ground. (B24)
- The pupal stage lasts seven days or longer, depending on
environmental temperatures. (B24)
