This caterpillar feeds on gumtree and wattle leaves. Once we found Black Slug Cup Moth 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 brought this caterpillar home to see what would happen.
