How Much Flies Are in the World?

The answer to the question, “How much flies are there in the world?” isn’t exactly a simple one. There are 17 quadrillion flies in existence in the world today, and all of them are the same size. The majority of them live as larvae, which means they are tiny, and they can be caught by predators, but they don’t live for very long.

Scientists estimate that there are approximately 120,000 different species of flies in the world. The total number is probably much higher. Flies are classified into families and genera, and species within one family or genus may share similar habits or lifestyles. Some of these species are helpful pollinators, while others serve as important food sources for many other animals.

Flies live a short life cycle and can reproduce rapidly. Females of the common house fly lay up to 120 eggs at once. Scientists have estimated that a pair of flies can produce as many as 191 billion house flies within five months. These numbers are based on the fact that a single female fly can lay around 120 eggs every day.

House flies are the most common flies found in homes. These insects can grow up to one-quarter inch in length and live for 15 to 25 days. These insects feed on dead organic matter.
