Food Plant: Betula pendula (Silver Birch), B.verrucosa (White Birch)

Egg: at the edge of a leaf

Mine: May - June

Notes: This is the early season miner on this plant; mines formed later in the season are due to Scolioneura betuleti. Blotch mines are formed at the leaf edge. There may be more than one mine in a leaf. The larva is pale green, with a brown head. A female was found in May 1942 in Ireland (Liston and O'Connor, 2005). The vacated mine illustrated is the second record for mainland Britain
