Life cycle observed on larval host plant Zephyranthes




Eggs are laid in batches like  most other moths and the number varies hugely. 




An early instar caterpillar. More reddish brown than black.

The colour turns darker as the caterpillar attains later stage instars.




A batch of caterpillars feeding on Rain Lily plant 




The later instar caterpillars usually feed on the plant from the top to bottom. They are observed eating the flower and the seedpods along with the leaves. 







Few grown caterpillars were seen feeding on orange pulp kept nearby. They continued to feed on them until the pulp became unavailable.
