case

Brownish lobe case that lies almost flat on the leaf, either at the upper or at the lower side. Case widest about the middle. Ventrally there is a distinct keel. Mouth angle 0°

Fleck mines rather large. The flaps of cuticular tissue that serve to enlarge the case are usually cut out of the upper epidermis. (contrary to C. ahenella and C. potentillae, that use tissue from the lower epidermis). The removal of these tissue flaps creates holes that are much larger than those that serve as an entrance to the mine.
