The differences between moths and butterflies fit into two categories: behavior and anatomy. For the most part, moths are nocturnal. They fly and feed at night. Butterflies, on the other hand, are diurnal, or active during the day. So the winged insect you see feeding from a flower in the middle of a spring afternoon is most likely a butterfly.
