Anatomy of a Cockroach with Picture

Anatomy of a Cockroach

Do you know what a cockroach looks like? Some people may be disgusted by these little creatures, but they are actually fascinating creatures. In this blog post, we will look at a cockroach’s anatomy. 

We will discuss the different parts of their body and what they do. We will also provide a picture of a cockroach for your viewing pleasure!

The cockroach has a head, thorax, and abdomen. 

  • The Head contains the cockroach’s mouth, eyes, antennae, and Brain. 
  • The thorax includes the cockroach’s legs and wings. 
  • The abdomen has the cockroach’s reproductive organs, digestive system, and excretory system.

The mouth of the cockroach contains two mandibles, or jaws. The mandibles are used for crushing and chewing food. The cockroach’s eyes are compound eyes made up of many tiny lenses. 

  • The antennae are sensitive to touch, taste, and smell. 
  • The Brain is responsible for controlling the cockroach’s movements and behaviors.
  • The legs of the cockroach are used for walking, running, and jumping. 
  • The wings of the cockroach are used for flying. 
  • The reproductive organs of the cockroach are used for mating and laying eggs. 
  • The digestive system of the cockroach is used to digest food. 
  • The excretory system of the cockroach is used to remove waste from the body.

Cockroach Body Parts

The Head of the cockroach houses its Brain, with sensors that help them detect light. They have two antennae that work as sense organs to help them identify food sources and other things around them by sensing chemicals or air currents from what direction they come in.

The mouth contains their mandibles used for biting into solid foods like plants, dead animals, etc. They also use their tough outer shell called “cuticle” to protect themselves from predators such as cats or dogs. Cockroaches are primarily nocturnal, which means they are active at night and stay hidden during the day.

The Head includes a long pair of antennae, a Brain, substantial mouthparts, and compound eyes. The antenna helps smelling and vibrate, and the Brain is used for sensing, eating, and chewing food mouthparts. The eyes have poor vision in the daytime and work powerfully at night time. That way, the cockroach is a nocturnal insect—the internal anatomy of the cockroach.

Thorax consists of 3 pairs of legs, two pairs of wings, and a plate behind the Head. They can move around with short spiky legs, and most adult roach have wings for the fly.

By the name, you can understand it is the lower part of the roach body which mainly consists of the reproductive and nerve system. These are the internal parts of a cockroach’s body.

How Do The Cockroaches Breathe?

Out of 4500 spices in the world, a cockroach can breathe differently. They do not need the Head for breathing. Therefore they breathe through an internal tube process called tracheae. This tracheae system brings oxygen directly to the cells. For this reason, they are even independent of mouth breathing.

Do Cockroaches Have A Brain?

We have already given you the roach head information that it can live without the Head for a week. But do you ever think about how this could be possible? Yes. This is possible because they can survive through a decapitation system which humans cannot.

As cockroaches are cold-blooded and their brains do not control blood pressure and breathing system, they do not even utilize their brains. They stay quiet, sit around, and die only after being affected by the bacteria or virus. Also, check out the life cycle of a cockroach with a diagram.

Are Cockroaches Clean?

This is a common question to all sufferers as it stays in a dirty dark place spreader of disease. However, you will be amazed to know that roach-like keep clean them all the time. Though they like to live in a warm, humid place, they maintain cleanness.

Why Do Cockroaches Never Die?

The roach breathing system is not dependent on the mouth or Brain they never die. But they died on their backs. Because when any insecticide is used, it directly affects their nervous system, creating muscular spasms and flips on their back.

Finally, this is about cockroach anatomy and their central body part. Although this is a concise discussion, removing cockroaches dramatically is the secret weapon.

Cockroaches are one of the most resilient pests, and understanding their anatomy is key to getting rid of them. Their ability to breathe without a mouth or Brain and their hardy exoskeleton makes them difficult to kill. However, knowing their weaknesses can help you develop a strategy to get rid of them for good.
