The Difference Between Moths and Butterflies

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. If you watch a large-winged, flitting insect make its way toward a candle at night, it's probably a moth.

Butterflies and moths also tend to hold their wings differently when they rest. You'll often see moths with their wings draped down their backs or spread out to the side. Unless butterflies are warming themselves in the sun, they typically hold their wings upright and folded together, perpendicular to their backs
