In certain areas of the world, cockroaches are also known as waterbugs. These are one of the oldest insects whose fossils are 320 million years old. They are commonly known for ‘leaving behind stinky smells’, attacking household food items, and are considered carriers of diseases and hence are despised everywhere they are found.
Their average length is 4 cm and they are mainly reddish-brown in color. These insects have yellowish margins on the pronotum. The body of the cockroach is distinctly segmented, dorso-ventrally flattened, and covered by a shining brown exoskeleton.
The body can be divided into three different parts such as the head, thorax, and abdomen. Wings that are darker than the body itself usually cover the dorsal body surface. By nature, cockroaches are nocturnal and omnivorous animals.
