Nauphoeta cinerea
Cinereous Cockroach, Speckled Cockroach, Lobster Cockroach
Nauphoeta cinerea is a circumtropical cockroach species native to northeastern Africa that has achieved global distribution through human association. Commonly known as the cinereous, speckled, or lobster cockroach, this species is frequently used as a laboratory model for studying social behavior, neurobiology, and reproductive physiology. Males establish strict dominance hierarchies that determine territorial rights and mating access, with social status mediated through pheromonal communication and acoustic stridulation. The species has been documented harboring Wolbachia endosymbionts of the F clade, which may provide nutritional benefits.
