Flies have occupied each and every country and they are familiar to both temperate, tropical along with every atmosphere varying from urban to rural. They are plentiful and available in nearly everywhere people reside. Consequently, they enjoy feeding on garbage and frequently present in animal feces, and due to that, they become a threat to human health.

Generalized Life Cycle of A Fly

Typical flies just like other several insects experience a four-phased life cycle and it starts a fertilized female immediately locates an appropriate site to lay their eggs. However the gestation period of their egg is just 24 hours, what’s more, infestations widens at disturbing rates. Larvae appear from their egg as they start to feed. Conversely, the larvae using their egg position as a food source, which is usually known as larvae, fee for four days so as to stockpile nutrients meant for metamorphosis.

Life Cycle Of Flies


1. Eggs

  • The period of laying to hatching takes around one day
  • Present in a cluster of up to three hundred.

2. Larvae

The larvae stage undergoes through three stages before it transforms to pre-pupal.

1st in star

  • Firstly feeds upon fluid that is derived from the body
  • Migrate into the body
  • The period of hatching the first molt is one day

2nd in star

  • Moves around within the maggot mass
  • First to the second molt takes one day

3rd in star

  • Substantially enlarges in size
  • Still moves within the mass
  • The second molt towards pre-pupa takes a timeframe of 2days

3. Pre-pupa

  • Moves out from the corpse searching for a proper pupation place and mostly in the soil
  • Does not eat at this stage
  • Changes into pupa
  • Duration of pre-pupa to pupa is four days

4. Pupa

  • Lives in the puparium
  • Goes through changes from larval body to form adult fly
  • Still does not eat at this stage
  • For pupa to appear it takes ten days

5. Adult fly

  • Mates on appearance from pupa
  • Eat only proteins from body fluids
  • Lays eggs on carcass
  • Appearance to laying eggs takes two days

Facts About Larvae

The primary feeding stage of the fly is the Larvae or maggot. Larvae are exceptional eating machines. Their front ends consist of mouth hooks which they use to rake in rotting flesh, shredded from the carcass. In addition to that, their nurture ends include a chamber, within which their posterior spiracles and anus are also situated including interior spirals; spiracles are used purposely for breathing.

There is muscular between their tails and heads, a single intestine, segmented body, and immense salivary glands. Besides that, they only wiggle during a carcass, dispersing putrefying bacteria and digestive enzymes that help them formulate their soupy environment.
