Cerodontha geniculata

Cerodontha geniculata (Fallén, 1823)


Upper-surface (rarely partly lower-surface) corridor, in about the centre of the blade. The larva changes direction at least twice (uo-down-up…). Normally the mine doesn’t reach the leaf sheath. Larva solitary, unless after fusion of several mines on a leaf. Frass in scattered grains, strings or pearl chains. Pupation in the mine; puparium mostly upper-surface.
