Roach fanciers of the United States waste little time. After this species was reported from certain areas of New York City, the collective conscience shifted to tracking them down for culture. Ectobiid and Blattid fanatic Daniel Kolesnick finally tracked down a population despite several disappointing attempts. Thanks to his dedication, everyone can enjoy this underappreciated member of a familiar genus! Renowned for its cold-hardiness, the Japanese roach does fine at room temperature. Maintaining this species above roughly 70 degrees Fahrenheit will keep the colony in “summer mode”, encouraging nymphs to mature and reproduce continuously without diapause. This is a very forgiving species that tolerates a wide variety of diets, substrates, and other parameters, though overly stagnant conditions are not preferred. Males are fully winged and females brachypterous, a unique dimorphism among all cultivated Periplaneta species. Perhaps over time this species may gain attention as an easy feeder species for those with temperature-variable rooms, as its “wild” environmental preferences seem more akin to those of some Parcoblatta species than the ubiquitous Periplaneta americana.
