Flies vs. Flies: Understanding the Differences and Similarities

Flies and flies are two words that are often confused with one another. Although they sound similar, they have different meanings and uses in the English language. In this article, we’ll take a closer look at what each term means, their differences and similarities.


Flies are insects that belong to the order Diptera, which means “two wings”. They have a pair of wings, hence the name, and are known for their ability to fly. They are common pests in many parts of the world and can be found in various forms and shapes.

One of the most common types of flies is the housefly. It is a small insect that measures about 6-7mm in length and has a grey-colored body with black stripes. Houseflies are known for their ability to spread diseases, such as typhoid fever, cholera, and dysentery, by feeding on human and animal waste.

Another type of fly is the fruit fly. This small insect is about 3mm in length and has a red or brown body. Fruit flies are commonly found in kitchens, where they feed on ripening fruits and vegetables.

Flies can also be used as a verb, meaning to move through the air with wings. For example, “the bird flew up to the tree” or “the airplane flies through the sky.”

Flies are a common subject in literature, art, and science. The famous book “Lord of the Flies” by William Golding is a literary masterpiece that explores the darker aspects of human nature. Even in ancient Egypt, flies were worshipped as gods and were seen as a symbol of strength, agility, and resilience.

Flies are important for the ecosystem as well. They play a crucial role in pollination and decomposition. Many species of flies feed on rotting organic matter, and this helps to break down dead plants and animals in the environment. They are also an important food source for other insects, birds, and mammals.

Flies have a fascinating life cycle. They start as an egg, then hatch into a larva, then a pupa, and finally become an adult. The life span of a fly can vary, but it usually lasts for only a few weeks.

Flies are often associated with negative connotations, such as filth and disease. However, they also have their uses, both in the natural environment and in human culture.


When we talk about “flies” with an ‘s’ at the end, we are referring to the plural form of the word “fly”. This means that there are multiple flies present.

For example, “The kitchen was infested with flies”. This sentence means that there were many flies in the kitchen. In this context, “flies” is the plural form of “fly” and is used to indicate that there is more than one.
