Opodiphthera eucalypti (Scott)
- A large caterpillar, 90–100 mm long
- In New Zealand, North Island, Nelson and Christchurch. Maybe also Dunedin.
- Caterpillar host plants are eucalyptus, pepper trees, silver birch, apricot, grape vines
- Damage can be extensive if there are large numbers of caterpillars
- For the adult to emerge from the hard, nut–like cocoon, it must rasp through the tough exterior. The sound of this process has been likened to a rat gnawing
