Simply put, butterflies are distinguished from butterfly moths based on their active time and physical characteristics. Butterflies are generally active during the day (diurnal), while moths are mostly active at night (nocturnal). The butterfly rests or rests with its wings upward, the moth rests with its wings spread. Butterflies usually have very beautiful colors, moths tend to be dark, dull or gray. However, these differences are always exceptions, so they can not be corrected scientifically
