What is a significant feature of the adult brown-banded cockroach?

The adult brown-banded cockroach is characterized by its distinct presence of wings, which is a notable feature among various cockroach species. Unlike some other cockroaches that may have reduced wings or none at all, the brown-banded cockroach has fully developed wings that extend beyond its body. This feature not only aids in its mobility but also differentiates it from other cockroach species that may lack such prominent wings. Furthermore, the wings are often used in mating displays and can be an indicator of the cockroach's maturity.

The other choices do not accurately describe significant features of the adult brown-banded cockroach. For example, this species does exhibit distinctive markings, as they typically have two light-colored bands across their darker bodies that can be quite prominent. Additionally, while they are relatively small, they are not the smallest among cockroach species, and their size does not define a significant characteristic. Lastly, while the brown-banded cockroach can glide short distances, it is not known for its flying ability like some other species might be, which could lead to confusion.
