Life cycleEdit


Larvae feed from August to June, initially in a whitish mine in the frond, and in the spring they leave the mine and burrow into a sorus, feeding on the sporangia. They later form a loose, portable case from empty sporangia and when fully grown in May the case resembles a misplaced sorus, especially on hart's-tongue fern (Asplenium scolopendrium). The larva is yellowish white with a brownish dorsa line and has a black head and black prothoracic plate.[1]

The following ferns have been recorded as food plants,[2][3]

Larva of another moth, Psychoides filicivora also feed on ferns. It has a pale-brown head and a pale-brown posterial margin, which has a split in the middle, compared with the black head and prothoracic plate of Psychoides verhuella.[4]


In a larval case, which is often against the midrib of the food plant.[3] Can be found in May and June.[5]


Single brooded, the moth flies in June and July, in early morning and late afternoon sunshine. Occasionally comes to light.[6] The grey to dark grey forewings have a violet reflection and lack the white tornal spot of Psychoides filicivora.
