Of the over 160,000 lepidopteron (moths, butterflies, and skippers) worldwide, the vast majority are moths. Moth antennas are feathery or thread like while butterfly antennas are tipped with bulbs or swollen. The bodies of moths are generally wider than those of butterflies. Both moths and butterflies are pollinators. Moths generally fly by night but some like the sphinx moth below feed by day or may be diurnal.  Most nocturnal moths are attracted  by light.
