Food Plant: Betula spp. (Birch), Corylus avellanae (Hazel)

Egg: Laid on a leaf

Mine: August - June

Notes: Only one case is formed and this is coated in leaf fragments. The final case is strongly curved and about 5mm long. Found at the margins of woodland rides and can be common in the South. The larva makes a typical 'pepper-pot' pattern as it feeds beneath the sapling leaves (as shown).
