Cockroaches, often known as roaches, are any of the 4,600 species among the oldest extant winged insects.

They still resemble the fossils from when they first appeared more than 320 million years ago. The Spanish word Cucaracha is the root of the English “cockroach.” The Cockroach has long, threadlike antennae, a flattened oval body, and a shiny black back.

Instead of pointing forward or downward like most other insects, the head is downward, and the mouthparts point backward.

While female cockroaches in some species are wingless or have rudimentary wings, male cockroaches typically have two pairs of wings.

In egg instances, the female produces eggs (called oothecae). They may be glued in safe spots or occasionally held protruding from her body.

The delicate white nymphs emerge after the female lays an egg case. Their exoskeleton gets brown as it becomes harder.

Cockroaches are exciting specimens in the biological laboratory due to their structure and size (some species have wingspreads of more than 12 cm [4.7 inches]).

 The Cockroach typically lives in tropical or moderate regions and loves a warm, humid, dark environment. Few creatures have evolved as pests.

The insect produces an unpleasant odor and destroys more material than it consumes. The roach eats plant and animal materials, including food, paper, clothing, books, and dead insects, particularly bedbugs. Roach control involves the use of insecticides.
