Ground Beetles, as this Coleopterous family is called, are for the most part terrestrial and hide in almost every conceivable place. They are particularly abundant under stones and objects on the ground and wherever other small invertebrates are found. Practically all of them are carnivorous and mostly nocturnal in habits. Many species are attracted to lights, and may be easily collected at night or by the use of light traps. The Carabids are predacious on worms, snails, caterpillars, grubs, maggots, and in fact almost any living animal that they can overcome. Because of their predatory habits they are considered beneficial, however a few of the genera are harmful in that they devour berries, seeds, pol1en, tender shoots and the foliage of plants.
