Grass Yellow belonging to Eurema genus
Grass Yellow butterflies belonging to the Eurema genus are members of the Pierid family of butterlies. This is a widespread genus with species from Asia, Africa, Australia, Oceania, and the New World. The genus is a taxonomist’s nightmare with over 70 species in the genus having been given more than 300 names. Some species, such as the Common African Grass Yellow, E. hecuba, have more than 80 synonyms.
I have very tentatively identified the butterfly I photographed as Eurema blanda or the Three-Spot Grass Yellow which is found widely in India. The host plants for this butterfly include Caesalpinia mimosoides and Bauhinia purpurea.
The Grass Yellow butterflies are relatively short-lived and several generations are completed in an year. The perpetuation of the species is a compelling imperative and the male butterflies which emerge a few days earlier than the females, quickly mate with the female butterflies as soon they emerge from the pupae so that the life cycle can be completed.
