Food Plant: Circaea lutetiana (Enchanter's Nightshade), Epilobium hirsutum (Great Willowherb), Epilobium montanum (Broad-leaved willowherb).

Pupa: Occasionally in a mined leaf or in a cocoon between the leaves or on the leaves.

Mine: June - July

Notes: A narrow contorted gallery leading to a whitish blotch with scattered frass centrally. The early gallery can merge with the blotch and there are often several to a leaf. The larva is light yellow, with darker thoracic legs. Mines on CCircaea lutetiana can occasionally reach very high densities, as here in an urban garden with large quantities of the plant.
