The Common Grass Yellow Butterfly lives up to its name. Found throughout all of India, this lepidopteran flies low and close to the ground in fields, and its wings are a pretty yellow with some subtle patterning. Their larvae feed on several different plants, but generally in the families of the spurges and legumes. 

During the summer, the butterflies’ wings become darker, a phenomenon known as seasonal polyphenism (this can also refer to other morphological changes such as size). It is thought that these color changes can help in better heat transfer or camouflage.
