Behaviour of Malayan Eggfly

[Common Mime]

This is not the first time I witness a female Malayan Eggfly "guarding" the eggs but did not know that she actually stays there even the eggs are hatched into larva. Have anyone encountered this behaviour for a butterfly before? Or I am the only one that do not know?

#1. Check the abdomen of this mother, very big and make her very difficult to fly . Finally settle down underneath a leaf of the host plant but not yet laying egg. Would love to witness the egg laying process in future, if time permits.

#2. Mother "guarding" the larvas.

#3. Closeup on the larvas. These larvas are not newly hatched, perhaps in the late 1st instar or 2nd instar rather.
