12.048 Psychoides filicivora (Meyrick,1937)
< back
feeds in mass of sporangia

 

Food Plant: Polystichum setiferum (Soft shield-fern), Dryopteris filix-mas (Male-fern), Phyllitis scolopendrium (Hart's tongue), Asplenium adiantum-nigrum (Black spleenwort) , A.trichomanes (Maidenhair spleenwort), Polypodium hesperium (Western Polypody)

Mine: throughout the year

Notes: P. filicivora appears to be continuously brooded, as larvae have been found in all months of the year. They usually feed on the underside of a fern frond under an untidy mass of sporangia, but on occasion, enter the leaf to make an extensive irregular blotch mine. Initially, filicivora occurred mainly near coasts, but it is increasingly recorded inland.

Data: 21.xi.2018, Mileham, Norfolk, VC28
