What is a distinguishing feature of female Turkestan roaches?

Female Turkestan roaches are identifiable by the cream-colored markings along the edges of their bodies. These distinctive markings are an important characteristic that sets them apart from other species or even males of the same species, which tend to lack such prominent coloration. The coloration serves not only as a means of identification but may also play a role in camouflage and mating displays within their natural habitat.

In contrast, while the size of female Turkestan roaches may vary, they are not consistently larger than males. Thus, size alone does not serve as a reliable distinguishing feature. The notion that they are entirely black is inaccurate, as their markings clearly differentiate them. Similarly, while some individuals may reach around 2 inches in length, size is less significant than the distinctive coloration when identifying female Turkestan roaches.
