Additionally, moths and butterflies have four wings that are almost always covered by colored scales, and a coiled proboscis for drinking liquids such as flower nectar.
They both eat nectar from flowers, and they supplement their diet with other liquids, like mineral-filled standing water and the juice from rotting fruit.
