This caterpillar feeds on gum and wattles leaves. We found Black Slug Cup Moth caterpillar caterpillar on blade grass in Macgregor Bushland during mid summer. Usually a caterpillar leaves its host plant only if it is fully grown and looking for a place to pupate. We then brought it home to see what would happen.

We put the caterpillar in a glass jar. Two days later, the caterpillar pupated on the side of the glass jar. The pupa was brown in colour. The second picture shows the moth came out from the pupa after two weeks.
