Eurema sari (36–42 mm), sometimes also called the Chocolate Grass Yellow, is a butterfly in the family Pieridae.
It is found in Southeast Asia.
Adults have a distinct brown apex on the underside of the forewing which instantly sets it apart from the other Eurema species found in Singapore.
This species is quite common, and can be found in many locations in the nature reserves as well as in urban areas in Singapore.
This is the subspecies Eurema sari sodalis found in Singapore.
