200 Psychoides filicivora
(Meyrick, 1937)Wingspan 10-12 mm.
Discovered in Ireland in 1909, this species has since been found in a number of English and Welsh counties, mainly coastally.
The larvae feed on ferns, especially soft shield-fern (Polystichum setiferum) and male-fern (Dropteris filix-mas), but are also found on Hartstongue (Phyllitis scolopendrium). The species is often found indoors.
The moths fly during the daytime in an extended generation throughout the summer. It is possible that the species has been introduced from abroad with imported ferns.
