Scale insect gall

Description:

Probably two galls - a small egg shaped brown gall with a small apical opening and arising from it a pale greenish-yellow gall which looked like a folded or unopened disc. The folded edge showed a waxy white substance.

Habitat:

Spotted on a leaf of a young broad-leaved eucalyptus tree.

Notes:

Thanks to Dr Lyn Cook for identifying these galls. The brown gall is the mother and the folded disc is a compound gall of males growing on their mother.
