Melangyna viridiceps is an Australian hoverfly, known as the common hover fly.

[2] It is one of the two most common hoverflies in Australia, alongside Simosyrphus grandicornis,[3] with which it has often been confused,[4] but can be distinguished by its all black thorax.

[5] The adult flies feed on pollen and nectar which they gather from flowers, while the larvae feed on aphids.

[8] Most recent sources,[9] however, do not record this species as being present outside of Australia.

Miller's 1921 mention for the Kermadec was found to be a misidentification for Simosyrphus grandicornis,[4] and Macfarlane et al.[7] failed to cite specimens or published reports for their claim of the species' presence in the Kermadec.
