The monarch arrived in New Zealand about 120 years` ago crossing the Pacific from North America. It is New Zealand's largest resident butterfly. 
Its caterpillar's food is the Swan plant (Asclepias physocarpa). Their live cycle is two weeks as a caterpillar, two weeks as a chrysalis and about two months as a butterfly. 
Female Monarchs have darker veins on their wings, and the males have a spot in the centre of each hindwing from which pheromones are released. Males are also slightly larger.

For information on pheromones visit http://en.wikipedia.org/wiki/Pheromones
