and Corylus colurna. They mine
the leaves of their host plant. They create a lower-surface tentiform mine, usually between two side veins. The pupa is made in a white cocoon in a corner of the mine. It is attached to both the roof and the floor of the mine. The frass
is deposited in an opposite corner.
