Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Also known as an Oleander Butterfly
As caterpillars, this species sequesters toxins from its food plant which are passed on from larva to pupa to the adult.
While feeding, it is a very bold butterfly, taking a long time at each bunch of flowers. It can also be found mud-puddling with others of its species and often in mixed groups.
The crow is distasteful due to those chemicals extracted from the latex of the food plants consumed in their caterpillar stage.
The adult butterflies sometimes congregate in groups of thousands at various sheltered coastal valleys from Brisbane to Townsville, Australia, to pass the winter in a state of hibernation.
The adult butterflies have been claimed to have a lifespan of eleven to thirteen weeks.
