Lifecycle of a housefly

Adults lay eggs in batches of 100 -150 eggs in manure heap,

rotting bodies, exposed food or feaces.

The eggs hatch into larva called maggots after a day.

NB: Some flies such as blue bottle fly hatch the eggs from in-

side the body and lay maggots.

 Maggots feed on decaying matter, grow quickly and turn

into pupa after 4-6 days.

 The pupa does not feed but grows from inside the pupa a

case called Cocoon.

 The adult crawls out of the pupa after about 4-5 days.
