Which type of cockroach is characterized by black adult females with wings that cover about half the abdomen?

The Oriental cockroach is indeed characterized by black adult females whose wings cover only about half of their abdomens. This species is often associated with damp or decaying organic materials and is commonly found in basements and other moist areas. The females are distinct not only for their dark coloration but also because their wings are not fully developed, leading to their characteristic appearance.

Recognizing the Oriental cockroach involves noting its size, with adults being around 1 to 1.25 inches long. The limited wing coverage in females distinguishes them from others, such as the American cockroach, which has fully developed wings, and the German and Brown-banded cockroaches, which differ in other important physical traits and behaviors. Understanding the unique features of the Oriental cockroach helps in effective identification and pest management strategies.
