For the first time, a large-scale migration of Common Grass Yellow was observed during the three-day butterfly survey which concluded at the Mudumalai Tiger Reserve (MTR) recently.
About Common Grass Yellow:
It is a small, charming butterfly species that can be found across Asia, North America, Africa, and Australia.
Scientific Name: Eurema hecabe
Habitat: They like to fly quickly, close to the ground, and are found in open grassy or bushy terrain, hence their name.
Features:
They have vibrant yellow wings that can range from a sultry sulfur shade to a lush lemon yellow, shifting with the seasons and their location. This is known as 'seasonal polyphenism'.
There is a black, broad, irregular outer marking on the forewing. The underside of the wing has various black marks with a yellow centre.
They are often seen in large groups, and the females usually fly about by themselves to find nectar from a wide variety of plants.
They are migratory in behaviour and are found migrating in large numbers across the entire Africa, throughout most of Asia south of the Himalayas.
