Food Plant: Polyphagous, on deciduous trees and shrubs.

Mine: July to April.

Notes: Larva mining leaves. The single case is progressively extended from the oral end. Rings of leaf-cuticle are added from the upper surface of the blotch, and project on the dorsal side of the case. The case lies prostrate against the leaf surface (as shown). The case is photographed on Birch (Betula). The case is similar to C.potentillae, but C.violacea makes punctures through the leaf.
