  Cryptocercus punctulatus is a wingless, wood-feeding cockroach endemic to montane forests of the eastern United States. It is one of the few subsocial cockroach species, exhibiting extended biparental care of offspring over multiple years. The species harbors obligate cellulolytic flagellate symbionts in its hindgut, transferred to neonates through proctodeal trophallaxis by parents. Its life history—xylophagy, social behavior, and gut symbiosis—makes it a key model for understanding the evolutionary origins of termite eusociality.
