The Giant Wood Moth of Australia is the Heaviest moth in the world, with some females weighing in at up to 30 grams. The larvae live in burrows inside the trunks of eucalypts, feasting on the wood. They spend up to one year within the tree before emerging as moths. Adults are unable to feed and only live for a few days. The heavy females lay about 20,000 minute yellow eggs before passing away.
