Beautiful black roach. These are said to be parthogenetic and the females reproduce without males. I do not know if males of this species exist, but at least in the hobby there seem to be only females. These love to burrow and eat through moist, soft rotting wood. I care for this species of roach like Pycnoscelus femapterus (I even keep the two species together in the same containers) and like P. femapterus I have had the same problem in that without dead oak leaves or wood these roaches started to die off.
