Food Plant: Plantago lanceolata (Ribwort Plantain)

Egg: Lower surface of leaf

Mine: June-July, October-April

Pupa: In a cocoon inside one end of the mine

Notes: Early mine a silvery gallery in lower epidermis. Subsequently a blotch on the upper epidermis. Internal spinning causes the leaf to pucker and often fold over the blotch, concealing it.
