Phyllonorycter parisiella Wikipedia
Phyllonorycter parisiella is a moth of the Gracillariidae family. It is found from the Czech Republic and Slovakia to the Pyrenees, Sardinia, Italy and Macedonia and from France to Romania.
The larvae feed on Quercus pubescens. They mine the leaves of their host plant. They create a medium-sized lower-surface tentiform mine with one strong fold in the lower epidermis. The roof of the mine is generally not completely eaten out, leaving a green centre. Pupation takes place within the mine in a cocoon that is almost entirely covered with frass.
