The larvae of this species are leaf miners and are known to feed on the leaves of Plagianthus divaricatus.

Adults of this have been observed on the wing in January, February, September and October, in coastal locations particularly in the preferred habitat of its host plant, that is salt marshes and sandbanks.

This species was first described in 1989 by Hans Donner and Christopher Wilkinson from specimens collected in Auckland, Queen Charlotte Sound and Invercargill.

[2][3] The larvae of this species are pale yellow in colour and are approximately 3mm long.

[2] The larvae feed on Plagianthus divaricatus and can therefore this species is found in the coastal habitat such as salt marshes and sandbanks which is favoured by that shrub.
