General Information

This species is difficult to distinguish from the recently separated C. robustella. Genital dissection is necessary for a conclusive identification, although the first generation appear around three weeks after C. robustella.


The larvae produce a narrow gallery leading to a squarish or triangular blotch. They then form up to three successive cones by folding the lobe of a leaf downwards.

Both sexes come to light.
