Food Plant: Origanum vulgare (Wild Marjoram)

Mine: early and late Summer

Notes: The initial mine is a small spiral (as shown at the top of the leaf, in the young mine illustrated). The mine then follows the edge of the leaf and a dark blotch is formed. Pupation is within the mine and the puparium is yellowish. Widespread, at least in the south of the UK.
