Chocolate Grass Yellow (Eurema sari)

Eurema sari (chocolate grass yellow) is a delicate butterfly in the family Pieridae, found across South and Southeast Asia. Smaller than the closely related common grass yellow, it has bright yellow wings with fine black margins, giving it a clean and vivid appearance. It is typically seen flying close to the ground in open fields, gardens, and along forest edges. The larvae feed on leguminous plants, while adults visit flowers for nectar, contributing to pollination and playing a role in maintaining healthy ecosystems.
