 All of the eight "Timema" species with a dorsal stripe have at least one host plant with needle-like foliage.Of the thirteen unstriped species, seven feed only on broadleaf plants.Four ("T. ritense", "T. podura", "T. genevievae", and "T. coffmani") rest during the day on the host plant's trunk rather than its leaves and have bodies that are brown, gray, or tan.
