1.The locust's brain can "calculate the accuracy" of the jump itself!
Scientists have found that locusts have a dedicated nervous system that helps accurately measure distance and jumping force, without the use of a full eye - resembling a tiny brain that acts like a built-in computer.

2. Locusts have ears on the "stomach," not on the head!
The location of the ear is on the side of the first abdomen, called the "tympanum," allowing it to pick up high-frequency sounds well suited to fleeing enemies or communicating with each other.

3. They can actually turn into "locusts, collapse the earth"!
When overpopulated, the body's dopamine hormones increase, causing them to change their behavior from a single locust to a herd of millions that eat everything in their face - like an actual catastrophic movie!

4. The locust's eyes have thousands of cameras in one eyeball!
The locust's eye is a "compound eye" made up of tens of thousands of small units, allowing it to see little movement accurately, so it can escape the enemy very quickly.

5. They communicate with each other by "sound from the legs"!
The sound we hear when grasshoppers sing comes from rubbing their hind legs against their wings, creating a "sound signal" to call a pair or tell a territory, not just a joke.

Who would have thought that the "insects we overlook" would have a brain that thinks faster than a calculator and has a life that changes the world? - Sometimes...Small things are not as small as they really think.
