Pale Grass Blue (Pseudozizerria maha) is a small Lycaenidae
(Gossamer-Winged Butterflies) butterfly, the same group of butterfly as
small copper (Lycaena phlaeas
daimio). The arrangement of the one or more rows of black
spots along the edge and inside differ in each species of Lycaenidae.
The larvae of pale grass blue feed on oxalis leaves. The photos below
show the life cycle of the butterfly.

It all started when the
butterfly laid eggs on the oxalis leaves. The butterfly shakes its
wings violently and made a circlular motion on the leaves.
The
egg was pearly white and cylindrical in shape. Radial grooves covers
all over the egg on top and on its sides.
In a few days after, the larva hatched. The larva eats away the
egg shells.
The larva soon moved away from the egg shell and start eating the
leaves.
The photo shows the larva when it
left the place it ate the part of the oxalis leave.
The
pupa is shiny pale green in color and attached itself on the twig of
the oxalis plant. The butterfly emerges in a several days from the
pupa.
