Range and habitat

In Japan, Galloisiana species prefer rocky areas and cool, moist environments, where they are frequently found near streams (often under rocks) in well developed forests. Unlike the Grylloblatta species of North America, they are not known to forage in snowfields.^[1] 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.^[2]

• Mahiru Mountains
• Mount Funagata and Mount Zao (volcanic cluster)
• Taishaku Mountains and Echigo Mountains
• Mount Agaki (volcano)
• Mount Haruna (volcano)
• Kanto Mountains
• Joshin'etsu Kogen Highlands
• Yatsugatake (volcanic cluster)
• Mount Myoko
• Hida Mountains
• Kiso Mountains
• Chikuma Mountains
• Akaishi Mountains
• Northern Ryohaku Mountains
• Southern Hida Kogen Highlands
• Suzuka Mountains

Specimens have also been collected in Shikoku, which are genetically close to specimens from the Suzuka Mountains.^[2]

Diet

Galloisiana species are generalist scavengers that feed on both plant and animal materials.^[1]
