Epicephala lanceolaria is a leafflower moth of the family Gracillariidae.

The only known host of the larva is Glochidion lanceolarium which is pollinated by the imago (flying moth).

[2] The moth is endemic to China and found in the provinces of Guangdong, Hainan and Hong Kong.

The eggs are laid in April and May on the flowers of Glochidion lanceolarium, with the adult moth pollinating the plant at the same time.

The larvae pupate within the mature fruit in March and the moths fly out in the following months to lay eggs on the newly emerged flowers.
