Habitat Species of this genus prefer rocky areas and cool, moist environments. This means that they are frequently found near streams, often under rocks, in well developed forests.
There are currently seven species that are known to occur in Japan. They are G. chujoi, G. harimensis, G. kawamurai, G. kiyosawai, G. nipponensis, G. notabilis and G. yuasai. Specimens have also been collected in Shikoku, which are genetically close to specimens from the Suzuka Mountains. Unlike the Grylloblatta species of North America, they are not known to forage in snowfields. They are most abundant in montane habitats in central Honshu. In central Honshu, Galloisiana specimens have been collected in the following mountains and mountain ranges: Mount Agaki (volcano), Akaishi Mountains, Chikuma Mountains, Echigo Mountains, Mount Funagata, Mount Haruna (volcano), Hida Mountains, the Southern Hida Kogen Highlands, the Joshin'etsu Kogen Highlands, Kanto Mountains, Kiso Mountains, Mahiru Mountains, Mount Myoko, the Northern Ryohaku Mountains, Suzuka Mountains, Taishaku Mountains, Yatsugatake (volcanic cluster) and Mount Zao (volcanic cluster).
Diet Galloisiana species are generalist scavengers that feed on both plant and animal materials.
