How long does it take for seeds to hatch from maggots?

How long does it take for a corn seed to emerge?
Adults emerge from the pupal case in about 7 to 14 days, mate, and begin a new cycle. The entire life cycle may require no more than 21 days, resulting in 3 or more generations each year. Later generations are of little to no economic importance to corn. Corn seeds attacked by seedcorn maggots may never emerge, thus reduced stands may be noted.
