Butterflies represent one of the two major groups within the order Lepidoptera, the other being the moths. The distinction between butterflies and moths is largely traditional rather than scientific — an arbitrary division based on appearance and behaviour. While almost everyone can recognise a butterfly, few could clearly define what separates it from a moth.
