Pieridae is a family of butterflies commonly known as whites and yellows. They are characterized by their predominantly white or yellow wings, often with black markings. This family includes many familiar species, such as the cabbage white and the sulphur butterfly. These butterflies are found worldwide, especially in temperate regions. They typically inhabit open areas like fields and gardens, where their caterpillars feed on plants, particularly those in the mustard family. Pieridae butterflies play an essential role in ecosystems as pollinators and are also important indicators of environmental health.
