Food Plant: Origanum vulgare (Wild Marjoram)

Mine: early and late Summer

Notes: The initial mine is a small spiral, which appears as a spot. The mine then follows the edge of the leaf and a dark blotch is formed (as shown, with the secondary feeding lines). Pupation is within the mine and the puparium is yellowish. Widespread, at least in the south of the UK.
