Cockroaches possess horizontal, oval-shaped bodies. The bodies of cockroaches are oily to the touch and may be cool or warm, depending on the temperature of their environment. The mind of a cockroach is little and is coated by a shield-like pronotum. A cockroach’s mouth is steered down and backward.

How Many Legs Do Cockroaches Have?

Cockroaches have six long, spiny legs that allow them to run quickly across just about any surface. The technical pads found at their tarsi are used for scaling surfaces and also allow for walking on ceilings and walls.

Some species of cockroaches have wings that are flattened against their backs, but not all cockroaches use these wings for flight.

Male versus Female Cockroaches

Male cockroaches are generally more compact than females. Female specimens often tend to be bigger and, in certain species, the female’s lack wings in which the men possess them. Cockroach eggs are encased in egg instances called oothecae, which are usually oval-shaped and dark brown in color.

Young cockroaches seem similar to adults but are light in color and don’t have wings. After devoting a few times, young cockroach nymphs become older adults.

Differences in Look Between Species

German cockroaches are brownish and roughly 13 to 16 mm long. Oriental cockroaches can become much bigger and are dark in colour. American cockroaches are reddish-brown in colour and are among the longest domestic cockroach species, measuring roughly 40 mm in length. Pennsylvania timber roaches measure roughly 20 millimeters in length.
