Flies are the most common species of the insects. They are tiny in size and are mostly found around the feces, rotting meat or sugary substances. Flies possess a very strong sense of smell, they can smell the odor of dead carcass from seven km away, but as it will take a long time for them to reach there, they prefer to go for the nearest bodies. The species of flies include several different kinds; such as house flies, blow flies, and flesh flies, etc. Among these kinds of flies, blow flies and flesh flies are most attracted to the dead carcass.

Blow flies:

The name of blow flies is derived from the old English term blow, meaning the type of meat with eggs found on it.

Flesh flies:

The flesh flies are slightly different from other kinds of flies as they hatch maggots instead of laying eggs, but they are common to blow flies as they are also attracted to the meat and wounds, etc.

Laying eggs and Hatching Maggots:

Once they are stuck to the dead carcass, blow flies lay eggs on them from where their reproductive cycle beings. Flesh flies also start their life cycle by hatching maggots on the recently dead carcass.


After laying eggs, the larvae of these flies feed themselves on the dead carcass for around 5-10 days. They suck the organic substance from the dead bodies that cause the decomposition of these dead bodies.


Maggots feed for about 5-7 days on the dead carcass and then got developed in the adult flies.


After getting fed on a dead carcass, blow flies leave them and wander in search of a dry place where they undergo the pupate stage of their lives. 

Adult flies:

In some time of leaving the dead carcass, they turn into adult flies.
