== Biology == This subfamily contains the most apomorphic ground beetles, displaying a wide range of forms and behaviors. The morphology of species within Harpalinae range from ant-mimics to charismatic members within the genus Pterostichus. Some exhibit rare feeding habits among ground beetles, including both omnivorous and even herbivorous species. Some members of Harpalinae, especially those restricted to the tropics, are considered to be arboreal. This variety of habitats has been considered to lead to the wide diversification of morphological traits.
