These wingless, humpbacked crickets are nocturnal. Unlike the camel crickets found in the midwest, this species has beautiful, symmetric markings. Why such ornate markings on a nocturnal animal? The answer was obvious to me when I saw this cricket on the light colored rock above on a moonlit evening. I never would have seen the cricket if I hadn’t been looking at the rock as the cricket ran across it. Another cryptic Sonoran species!
