The Colias philodice, commonly known as the clouded sulfur butterfly, is a species found primarily in North America. It is characterized by its bright yellow wings, which often have orange spots. The wingspan typically ranges from 1.5 to 2.5 inches, and these butterflies are commonly seen in open fields, meadows, and gardens. The larvae of Colias philodice feed on various plants, particularly those in the legume family, such as clover and alfalfa. Adults are often spotted during the warmer months, as they are attracted to nectar from flowers. This species plays a role in pollination, contributing to the health of ecosystems.
