Which type of cockroach has wings that do not cover all of its abdomen and cannot fly?

The Oriental cockroach is characterized by wings that are shorter than its abdomen, which prevents it from flying. This type of cockroach has a glossy, black or dark brown appearance and its wings do not extend fully to cover the entire body, a distinct feature that sets it apart from other cockroach species. In contrast, the German, Smokey Brown, and Brown Banded cockroaches have wings that generally cover more of their abdomens and, in some cases, possess the ability to fly. Understanding these anatomical differences is crucial for pest control technicians when identifying and managing various cockroach species effectively.
