Conehead grasshoppers can be found on grasslands, prairies, pastures, meadows, fencerows, and in vegetation along railroad tracks. Long-horned grasshoppers are insects with incomplete metamorphosis. The female lays eggs in autumn. The next spring, eggs hatch to nymphs, which look like miniature adults without wings. As they grow, they molt their exoskeletons several times. They grow wings in the last stage of development.
