The larvae of this species are pale green with a transparent skin and a dark head.

[2] Adults are brown with various white markings outlined in black on each forewing.

[3] In Australia and New Zealand the larvae feed on the undersides of the fronds of various Polypodiophyta species, including common maidenhair fern (Adiantum aethiopicum), Austral bracken (Pteridium esculentum), and bat's wing fern (Histiopteris incisa) and lives in a sparse web.

[2] Larvae were first found in England in 2013, near Hern, Dorset and so far have been found feeding on bracken (Pteridium aquilinum), broad-buckler fern (Dryopteris dilatata) and hard fern (Blechnum spicant).

In 2009 the moth was found at Merritown Heath, Hurn, Dorset and since then across southern England to Norfolk.
