The host plants of the species include Cassia species (e.g., C. fistula; C. javanica or C. roxburghii; C. bakeriana), Gnidia glauca, Senna species (e.g. S. alata; S. auriculata; S. garrettiana), Crotalaria species, Ormocarpum cochinchinense, Sesbania species and Colocasia.

The development period from egg to adult is 22 to 29 days allowing up to 11-12 generations a year.

Larva: "Long, somewhat depressed, rough, green, with a white lateral line and above it a black line more or less conspicuous, formed by minute black shining tubercles.
In short, this larva in very like a big specimen of a Eurema hecabe".

Pupa: "Much stouter (i.e. than that of Eurema hecabe, and the keel formed by the wing-cases much less pronounced.
The normal colour is pale green with a yellow lateral line.
We have never found it on any plant except Senna occidentalis.
It habitually rests on the upperside along the midrib, like almost all Pierine larvae."
