Food Plant: Rumex (Dock) , Lysimachia vulgaris (Loosestrife), Persicaria hydropiper (Water-pepper) P.maculosa (Redshank), Fallopia convolvulus (Black Bindweed)

Egg: Usually lower surface

Mine: May-July;August-September

Pupa: In the final leaf roll made by the larva

Notes: The inital mine leads to a Phyllonorycter blotch on the undersurface of the leaf. The larva then rolls the edge of the leaf, making two or more rolls. The larva has two distinct forms and habits - the first phase is a sap feeding phase and the second is tissue feeding (Heckford, 2021). An initial underside blister mine and a leaf roll on Persicaria sp. in a damp meadow.
