<human>:  What is the difference between a butterfly and a moth?
<bot>: The main difference between a butterfly and a moth is that butterflies are generally more colorful and have more distinctive markings and patterns than moths, which are usually duller in color. Butterflies also tend to be diurnal and fly during the day, while moths are typically nocturnal and fly at night. The wings of butterflies also have a more delicate and smooth appearance compared to the furry, feathery wings of a moth.
