Idioglossa metallochrysa is a very small species of golden-metallic coloured moth of the family Batrachedridae living in a subtropical highland climate, at least in Australia, and of which the caterpillars feed on the plant Cheilocostus speciosus, at least in Indonesia.

[1][3] There are three syntypes, two are kept at Australian National Insect Collection, and one at the Natural History Museum, London,[3] courtesy of Edward Meyrick.

[1] The Australian entomologist Ian Francis Bell Common classified it in the subfamily Stathmopodinae of the family Oecophoridae in 1996.

The both pairs of wings have long hairs coming off them, which Jefferis Turner terms cilia in his description, in the fore-wing these are ochreous coloured, dorsally grey, whereas in the hind-wing they are "grey-whitish".

[3] The locality it was collected, Tamborine Mountain,[1] has a cool subtropical highland climate, with the annual rainfall of about 1,550 mm.
