This small roach is quite unique in the hobby. Currently, it is both the only available member of the subfamily Perisphaeriinae as well as the only available roach species capable of rolling up into a ball. The newborn nymphs are very tiny and olive colored but turn black with their next molt. Before doing so, they will cling tightly to their mother. It is believed that in related species, the mother actually nourishes the babies by emitting fluids through her leg joints. After this sensitive period, the nymphs will behave like typical roaches, feeding and exploring on their own. When disturbed, the adult females and nymphs will roll up into a ball in a manner exactly like those found in the unrelated roly-poly isopods. Mother roaches that are nursing babies will even roll up to protect their young! This species prefers a well-ventilated enclosure with bark to hide under, and they show a definite preference for apples as a food item. Considering all of its special traits, this is definitely one of the most unique roaches available!
