Cornus mas
The larvae feed on "Cornus mas", "Cornus sanguinea", "Lonicera alpigena", "Lonicera nigra", "Lonicera xylosteum", "Lonicera chrysantha", "Rhamnus catharticus", "Rhamnus frangula", "Symphoricarpos albus" and "Viburnum lantana". They create a lobe case of about long. The mouth angle is 0°, causing the case to lie flat on the leaf. The case is gradually enlarged by the addition of rings that are cut out of the lower epidermis of the mine. In Great Britain, the larvae live for two years.
