fern

The fern looks more like Dryopteris dilatata than male fern - if you were to duplicate the record into the Plants section you could get confirmation - I'm not always great at ferns.
The Biological records cente Database of Insects and their Food Plants only records Lady fern

Dryopteris sp.

Thank you for your comment. The gall-causer is the same on a number of ferns including D. felix-mas, D. affinis, D. dilatata, D. carthusiana and several subspecies (Redfern & Shirley: British Plant Galls).
