⁂ Fabricius was primarily a systematist and originated the maxillary and cibarian system of classification of insects in which mouth parts were used to separate the order. He likewise described a large number of North American insects. In his works, Fabricius described many Australian and New Zealand insects brought back by Captain Cook's voyages around the world.
