Habitat: Males sing from large cracks on the face of badland clay cliffs and escarpments, at a height of about 10 m from the ground.
Life cycle: One generation per year. Probably no egg diapause because adults are singing by late June.
Season: Adults can be found from June to August.
Name derivation: Lakota: "makhosica" = "badlands"; G. makhosica's preferred habitat in the Badlands National Park, which is inhabited by the Lakota people.
