how long does it take for a maggot to hatch from an egg
Instars (Molts) In the life cycle of all arthropods, there are several molts, or instars, in which the insect will shed its exoskeleton to evolve into a new form. In the life cycle of the maggot, there are three instars before it reaches its pre-pupa phase. Before the beginning of the first instar, the mature fly will lay more than 300 eggs in a carcass, each one holding a fly larva. Once the eggs are laid, it takes only a single day for them to hatch. During the first instar, the larva migrates into the body (carcass) and feeds on the body fluids.
