Digitivalva reticulella (Hübner, 1796)
mine
Young larvae make a narrow corridor, starting in the leaf base, with a narrow frassline that often lies at one side. They can leave the mine and restart elsewhere. Later mines or mine sections are much wider; most of the frass is ejected (though grains may get stuck in the plant hair cover). Older larvae live free among the flower heads.
