Birdwing
Northern Birdwing -
Ornithoptera priamus

Bb

These are amongst the largest species of Australian butterfly and they are found only in the rainforests of northern Queensland. The females lay their eggs exclusively on the leaves of a few species of broad-leafed climbers because that is the only food the caterpillars will eat.

Males and females are very different in both colour and size.  Males are the smaller animals with a wingspan of about 10-12 cm and bright, metallic green and black wings, while females have brown wings and a wingspan of up to 15 cm.  Like all butterflies the adults feed on nectar from flowers through long, tubular mouthparts.  In the process of feeding the butterflies will move around a lot and pollen from the flowers will fall on their wings and body.  When they move to the next flower the pollen will be transferred and thus fertilise the plant.
