The gray bush-cricket is only found in the dunes. As its name indicates it is a gray animal, sometimes having a green upper side. The species is a good flyer, as opposed to other bush-crickets. The animals often sit under bushes or plants, usually well camouflaged. Their ovipositor (for laying eggs) is 8 to 11 millimeters long. Their song is a continual series of short zooming sounds, sounding like a watch being wound up. Gray bush-crickets are active particularly in the afternoon and evening.
