Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Also known as the Blue Moon Butterfly
Eggfly butterflies are some of the most territorial butterflies around.
They will choose one spot that they consider to be theirs, and chase away any intruders including Cairns Birdwings which are more than twice their size.
They will always return back to the same spot. They may stay at in the same spot for many days.
The Eggfly also exhibits a rare example of maternal care in butterflies, as they are known for guarding leaves where they have laid eggs.
