Insects are fascinating. They're tiny, they have wings, they live everywhere, and they're just so much fun to be around! But did you know that there are still some things about insects that you probably didn't know?

If you've never paid much attention to insects before, now is your chance to learn something new! Here are 7 facts about insects that you probably didn't know:

1. They don't have a nervous system. Insects have individual nerve cells, but no brain or central nervous system like humans do. Instead, their brains are made up of groups of nerve cells called ganglia.

2. They don't have blood: Their bodies are filled with hemolymph instead of blood! Although it's similar to hemoglobin in how it carries oxygen from the tissue surfaces to the organs, hemolymph is not as viscous as human blood and therefore does not flow as easily through narrow vessels and capillaries (the thin tubes that carry fluids inside and outside of the body).

3. They breathe through holes in their exoskeleton called spiracles—just like us! These openings allow them to exchange gases without having any kind of respiratory apparatus—which would cause them to suffocate if they had lungs instead of gills!

4. They are capable of flight. Yes, they can fly! They have wings (sometimes) and they use them to get around. You might be surprised to find that some insects have wings at all—in fact, there are more than 1 billion different species of insects worldwide!

5. They have eyes on their feet. No joke! Some insects have eyes on their feet so they can see what's going on around them while running from predators or looking for food (or both!). This is especially useful when hunting for prey in dim light conditions such as caves or underground tunnels where other senses would be useless without vision).

6. Insects have very specific diets based on what kind of environment they live in and what kind of food source is available nearby—that's why some kinds of bugs like caterpillars are found only in specific areas where certain plants grow naturally; others like ants can go for weeks without eating at all if there isn't any food around!

7. Insects live for a long time. Insects have lifespans ranging from just a few days to over 30 years—and some species live even longer than that! Some species can even live over 40 years! This means that if you bring home a bug as a pet, it will probably grow up with you. And once it does find its way into your home, it will probably stay there for a long time too—at least until it dies of old age!

Insects are the most diverse group of animals on Earth. That's right—they're so diverse, in fact, that they have more than 1 million species! They can be found in every continent except Antarctica, and they live in all kinds of places: deserts, rain forests, tundra, even cities like New York City. They eat just about anything: flowers, fruit trees… even each other! And while they may seem like tiny little bugs to your eyes, if you were to look at them up close you'd see that they're actually quite big—they can grow as long as a human finger! That's right—even the largest insects are only about the size of your thumb! However, that doesn't mean that they're not important to our ecosystem. Insects play a key role in the cycling of nutrients through their ecosystems and help break down decomposing matter into fertilizer for plants and other animals.

In Conclusion

There are some things in life you don't expect to learn from a blog, but this is one of them. As it turns out, insects can be just as fascinating as anything else--and the amount they have to teach us hasn't even begun. From their incredible strength to their brilliant camouflage and beyond, these tiny critters are pretty impressive.

Hopefully, I've dispelled some of the myths that surround insects and showing you the many interesting and useful things they do in the world. Insects aren't always out to get us; they're simply doing their best to survive, just like any other species on the planet. And if we continue to work with them, instead of against them, we might have a chance of not only surviving alongside them, but perhaps even improving our world in the process. After reading this, you may never look at them the same way again.
