Which cockroach is known for being the largest species?

The American Cockroach is recognized as the largest species among common cockroaches. It can grow up to 3.5 inches long and has a characteristic reddish-brown color with yellowish markings on its thorax. This species is often found in warm, damp environments, including sewers and large buildings, contributing to its prominent size. Its wings allow it to fly short distances, setting it apart from other cockroaches, which tend to be smaller and less mobile in the air. In contrast, other cockroach species, such as the German and Oriental cockroaches, are notably smaller, measuring around 1 to 2 inches in length. The size difference is significant and is a distinguishing feature of the American Cockroach, making it identifiable and important within discussions concerning pest control and management.
