As soon as the maggots hatch from their eggs, they begin to feed on decomposing animal carcasses or any trash which is present at the place of their birth. After a few days, they become a pupa, and this pupal stage stays for the longest time in their developmental cycle. During this time, they tend to move to a drier place where they bury themselves in the soil. After two to three weeks, an adult is formed from the pupa and mate to begin the lifecycle again.
