Common grass yellow (Eurema hecabe) is a small, bright yellow butterfly in the family Pieridae, widely distributed across Asia, Africa, and Australia. It is easily recognized by its vivid yellow wings edged with black borders, which vary in width depending on the season. Active and fast-flying, it is commonly found in gardens, grasslands, and open habitats, often seen fluttering low among flowers. The larvae feed mainly on legumes (Fabaceae), while adults help pollinate various plants, making this butterfly both ecologically important and a familiar sight in many tropical and subtropical regions.
