Eggs laid, 30-100 per female fly. Hatch in two days.
Larva stage 8 to 24 days. Larvae can survive in low oxygen conditions.
Pupa stage one to two days.
Adults breed only once, usually right after emerging from the pupa.
Adults die after 3 to 4 days with no food. If food is available, they will

No wonder the suckers are so hard to get rid of.
