Whatever your opinion on flies is, you have to admit that while these insects may be pests, their existence is quite remarkable. You are probably familiar with the common types of flies such as the housefly, but you may not know that there are a lot of kinds of flies in the world! With billions of each kind of fly in the world, you may wonder what they eat in order to survive. Food intake for flies varies among different species, but some of the food sources for flies tend to overlap. If you are interested in learning more about what flies eat, read on for some interesting information.

Common types of flies you can find at homeCommon flies you can find at home include the housefly, the blow fly, the fruit fly, the phorid fly, the drain fly and the fungus gnat.

The house fly

The housefly is the fly that you are probably most familiar with. They are usually unwanted pests, and they can cause some issues in the home if a large population of flies enters one’s house. For food, houseflies rely on their tiny mouths to get food. Scientists have compared the fly’s mouth to a sponge because their mouths absorb whatever food is near by. Once absorbed by the mouth, the fly uses its tiny tongue to help swallow the food.

They need liquid food

An important fact to realize is that because flies have such tiny mouths and tongues, they must turn their food into liquid before they can digest it. They are typically drawn to liquid waste, but they can turn solid food into liquid by saturating it. Their food may not seem particularly appealing to humans, but flies depend upon easy sources.

Fruit flies and other flies

Most species of flies prefer waste and pet waste for food. Some species, like the fruit fly, are a little different. Fruit flies actually get their name from the food they eat. It is easy to identify fruit flies because they are often seen flying around decaying fruits and/or vegetables. Fruit flies land on the fruit and behave similarly to the common housefly by absorbing the juice of the dying fruit through their mouths.

    i found a fly that cant fly inside my house. i was wondering what would i give it to eat?

  2. admin:

    Hi Veronica Smith,

    What type of fly is it? You can always try to give it liquid sugar or pieces of fruits, vegetables or even leftovers. You don’t need much to feed them and the fly probably won’t live that long anyway.

    wait i thought flies eat trash

  4. admin:

    Hi Nicoleundrw,

    Not trash itself but liquids from rotten food or any other organic matter that is decomposing.

    When I was little I loved animals! I found a hurt fly so I helped it, I gave the fly cheese. The fly crawled to it and ate a little. Why couldn’t I see pieces missing?

    Hi Audrey Kate,

    The reason is because flies turn their food into liquids first before drinking it. We, on the other hand, bite our food and that is the reason you can see missing pieces.
