This is a popular question we all have asked ourselves at least once in our lives: how many legs do cockroaches have? To make the answer short and clear: cockroaches have six legs and each pair of legs is attached to one side of their thorax. Every pair of legs has a specific name: prothoracic, mesothoracic, and metathoracic.
How many legs do roaches have?
A cockroach has six legs. And, as told above, each pair of legs has a specific name.
Prothoracic legs are closer to the head of the cockroach and they are really small compared to the others. Mesothoracic legs help the cockroach to earn speed or slow down.
The metathoracic legs are located at the back of the thorax and they help the insect to move forward. There’s a part on the upper side of each leg called coxa that attaches the legs to the thorax of the insect. The leg of a cockroach can grow back from scratch if they lose it.
Interesting right? I invite you to read if you want to know even more about the body of a cockroach.
The head of a cockroach holds its eyes, mouthparts, antennae, and part of its nervous system. Have you heard about the myth of cockroaches living after they lose their heads? Well, it is no myth, since the other parts of their nervous system are located throughout their body, cockroaches can live at least one week without a head.
The antennae of these insects help them to feel and smell the world around them. Cockroaches continuously clean their antennae, but scientists still don’t know why they do it.
Obviously, the mouthparts of a cockroach are different from mammals but these parts work just the same for them: these insects cut, chew, and grind their food. Moreover, cockroaches also have two lips called labrum and labium.
On the head, there’s a small plaque called pronotum which is an important part of these insects since here you can find the markings that differentiate each species from one another.
As explained before, the in the thorax of a cockroach we find the legs. Additionally, on the thorax, we also find the wings. Almost every type of adult cockroach has two pair wings but most of them don’t use it to fly.
The last part of the anatomy of a cockroach and an essential one since it contains the organs of the insects. A cockroach has heart and a circulatory system, a digestive system, reproductive organs, and sensory organs. Thanks to its sensory organs, cockroaches can feel whatever is behind them, and that’s the reason why they are so difficult to catch!
To conclude, cockroaches have three pairs of legs attached to their thorax. The thorax is only just one of the three essential body parts of these insects, the other ones are the head and the abdomen. In the head, we can find the mouthparts, antennae, eyes, and part of its nervous system. In the abdomen, we find the reproductive and sensory organs, and the digestive system and circulatory system of a cockroach.
Overall, these animals have evolved to live in every possible era, but that doesn’t mean they’re impossible to eradicate.
