Chirosia betuleti

The larvae of the fly Chirosia betuleti cause galls to form on ferns, and in particular on Male-fern, Lady-fern and Buckler-ferns. Eggs are laid in the tip of the fronds, and the resulting larvae tunnel into the main stalk causing it to twist and the pinnae to become bunched and distorted like a mop head. Some of the pinnae may turn brown and die.
