Life Cycle of Fly on Dead Carcass

The flesh and blow flies are two types of flies that are commonly attracted to the bodies of the dead animals. The maggots (larva stage) will feed on the tissue of the carcass. While it may sound unpleasant, it is actually beneficial since they help speed up the process of decomposition. If there are maggots or flies in your house, it is usually an indication that there is a dead creature in your attic or wall.



The Life Cycle of the Flesh or Blow Flies
The flesh flies and the blow flies will be attracted to the body of an animal that died a moment ago. They will then lay at least 300 eggs on the body. The eggs will then hatch into a larva in just a single day. During the initial stage of the maggots, they will first feed on the fluids that are being released by the dead body. They will then move inside the body and it will only require 2 days to increase their size.

The fly will then enter the pre-pupa stage. From the corpse of the animal, they will have to look for a more suitable site before they transform into a pupa. Normally, they will not eat during this stage. It will take at least 4 days before they turn to pupa. The pupa is basically living in the puparium. During this time, they will go through a certain transformation in order to achieve the form of an adult fly. It will require 10 days for them to emerge into a Naples fly. It will basically take 2 days before they will be ready to lay eggs again.

The Maggot Stage
Maggot or the larva is the stage when the Florida fly will consume a lot of foods. During the first time they hatch from their eggs, they measure at approximately 2mm. They will then grow to at least 5mm before they will shed their old skin. During the second stage of larva, their size will increase to roughly 10mm before they will shed their skin again. At the third larva stage, their body can extend to up to 20mm. Aside from their change in size; the form of the larva will also go through some transformation. The best way to differentiate the various instars of larva would be their posterior spiracles.

The capacity of the maggots to eat is simply astounding. They are equipped with the mouth hooks that allow them to feed on the decomposing flesh. On the rear part of their body, you will find their posterior spiracles. This is mainly used for breathing purposes. The position of the spiracles simply means that the fly has the capacity to eat and breathe for 24 hours per day. The female blow Naples fly has the capacity to produce at least 300 eggs at a single time. Due to the number of male flies, they have the ability to lay a considerable amount of eggs that can consume about 60% of the dead human body in just a matter of 1 week.
