Which characteristic describes adult female oriental cockroaches?

The characteristic that accurately describes adult female oriental cockroaches is that they are black with wings covering about half the abdomen. This is a distinctive feature of this species, setting them apart from other types of cockroaches. Adult females typically have a dark coloration, which can sometimes appear to be almost shiny, and their wings are not fully developed to the extent that they cover the entire body. Instead, they are shorter and cover approximately the rear half of their abdomen, reflecting their less active nature compared to their male counterparts, which have fully developed wings and are more inclined to fly.

In contrast, the other descriptions do not align with the physical traits of the female oriental cockroaches. For instance, claiming that they are brown with entirely covering wings or red with a slender body misrepresents their actual appearance, while stating they are dark gray and wingless does not accurately depict the characteristics of adult females of the oriental cockroach species.
