The greater glider (Petauroides volans) is a small gliding marsupial found in Australia. It is not closely related to the Petaurus group of gliding marsupials but instead to the lemur-like ringtail possum (Hemibelideus lemuroides), with which it shares the subfamily Hemibelideinae.
The greater glider is nocturnal and is a solitary herbivore feeding almost exclusively on Eucalyptus leaves and buds. Like its relative the lemur-like ringtail, the greater glider is found in two forms: a sooty brown form, or a grey-to-white form.
The greater glider is found in eucalypt forest from Mossman, Queensland, to Daylesford, Victoria.
