The Guava Moth is brown to purple in colour, with a black kidney-shaped spot near the centre of each forewing. When it open the forewings, we can see its bright yellow hind wings. Each hind wing has a large black spots near the wing tip.

Length 60mm 
 
On Feb 2006, we found a caterpillar resting in a gum tree stem. It was well camouflaged and hard to be noticed. After we took the 1st picture, aw came closer and it dropped onto the ground. We picked it up by a leaf and took the second picture. We then brought it home with some gum tree leaves as it food. 
 
Few days later, it turned into a pupa on the bottom of the container, covered with leaves.
