Three-spot Grass Yellow

Eurema blanda


The sexes are alike. The shape of the outer margin is not completely rounded on its hindwing and is wavy on forewing. The irregular black outer margin on the upper surface of its forewing is slightly different to that of the previous species. The hindwing has a thin black outer margin. Its underside is usually heavily marked in comparison to the previous species and its cell end patches are larger and have a yellow area in the middle. The basal parts of the forewing cell have three black markings. They bare the chocolate colored apical patch on the forewing more frequently than the Common Grass Yellow, and this patch is also larger.


Its behaviour is similar to that of the Common Grass Yellow, except that males are often found mud puddling. Females lay eggs in large clusters and sometimes it climbs higher than its usual flying height to lay eggs. Although this butterfly is found in open vegetation, it requires much wetter conditions. Hence, it is more widespread in the wet zone. It is more numerous than Common Grass Yellow along rain forests paths. It is less abundant in the hills.
