Australia’s biggest moth is the Hercules Moth (Coscinocera hercules) found in New Guinea and Northern Australia. It has a wingspan of about 27 cm (10.6 in) across. These moths do all their eating as caterpillars, so the adults don’t need to feed at all. They just burn off the ‘baby fat’ and devote their last week or so of life to finding a mate.
