Chromatomyia centaurii
The larva of the Agromyzid fly Chromatomyia centaurii mines the upper surface of the leaves of Common Centaury. The mine starts as a gallery, but this is then commonly engulfed by the blotch that then follows. This mine is typically in a basal leaf, near to the ground, but may also move into the stem.
