Did you know that the average lifespan of a housefly is only 24 hours? That’s right, just one day! In that short time, they manage to cram in a lot of activities. For example, did you know that female houseflies can lay up to 500 eggs in their lifetime? And that each of those eggs hatches into a larva within 24 hours? That’s a lot of baby flies!

In addition to reproduction, adult houseflies also like to eat. A lot. They feed every few minutes and can ingest up to 150% of their body weight in one day! No wonder they only live for 24 hours – they practically work themselves to death!
So, the next time you see a pesky housefly buzzing around, take a moment to appreciate its incredible life cycle. Even if it is annoying, it’s still amazing what such a small creature can accomplish in such a short amount of time.
What is the life cycle of a housefly?
As we mentioned before, the life cycle of a housefly is pretty amazing. Here’s a quick overview:
The eggs are laid in something sweet or decaying, like garbage or fruit.
The eggs hatch and the larvae (maggots) start to eat.
The maggots turn into pupae, which is when the fly starts to develop its wings.
Finally, the pupae turn into adult flies, and the cycle begins anew.
As you can see, the life cycle of a housefly is pretty incredible. From eggs to adults, they go through a lot of changes in just a few short days!

Other interesting things do we know about the housefly?
The longest recorded lifespan of a housefly was 28 days
As we mentioned before, the average lifespan of a housefly is only 24 hours. However, the longest recorded lifespan of a housefly was 28 days. That’s right, four whole days longer than the average!
So, what makes this particular fly so special? Well, it turns out that this fly was kept in captivity. In other words, it didn’t have to worry about predators, parasites, or any of the other dangers that flies face in the wild. As a result, it was able to live a much longer life than the average housefly.
Of course, even in captivity, 28 days is still a pretty short lifespan. But it just goes to show that with the right conditions, even a housefly can live a surprisingly long life.
What do houseflies eat?
As we mentioned before, houseflies love to eat. But what, exactly, do they like to eat? Well, it turns out that houseflies are attracted to anything that is sweet or decaying. This means that they are often seen buzzing around garbage cans or fruit that is starting to rot.
In addition to sweet and decaying food, houseflies also like to eat other insects. In fact, they have been known to eat up to 500 other insects in their lifetime! So, if you see a housefly near a spider web, there’s a good chance that it’s looking for its next meal.
What do houseflies do?
In addition to eating and reproducing, houseflies also like to fly. A lot. In fact, they can fly up to 60 miles per hour!
But why do they like to fly so much? Well, it turns out that flying is a great way for them to find food. By flying around, they can cover a lot of ground and find the sweet or decaying food that they like to eat.
In addition to finding food, flying also helps houseflies stay away from predators. After all, it’s much harder for a predator to catch a fly that is constantly moving!
Do houseflies carry diseases?
Unfortunately, the answer to this question is yes. Houseflies can carry many different diseases, including typhoid fever, cholera, and dysentery. This is because they often land on food that is contaminated with feces or other hazardous materials.
As a result, it’s important to make sure that any food that you eat has not been contaminated by a housefly. If you see a fly near your food, it’s best to throw it away to be safe.
How many species of houseflies are there?
There are thought to be around 24,000 different species of houseflies. However, only a handful of these species are found in homes and other buildings.
The most common type of housefly is the Musca domestica, which is the species that we have been discussing throughout this article. This fly is found all over the world and is responsible for spreading many diseases.
Other common species of housefly include the Musca sorbens, which is found in Africa, and the Musca vetustissima, which is found in Australia.
My cat tracks down, kills and eats flies. Is that safe?
Yes, it is safe for your cat to eat flies. In fact, it’s a good thing! By eating flies, your cat is helping to keep your home free of disease-carrying pests.
Of course, you should always make sure that the flies your cat is eating are not contaminated with anything harmful. If you have any concerns, you can always speak to your veterinarian for more information.
In conclusion, houseflies are interesting creatures that most people know nothing about. But since they are so common, knowing as much as you doesn’t just tickle your brain, it increase your awareness of the world we share.
