A species with not so many records in the past, but since the recent quest for leafmining species it seems to be fairly common.
Native
The larva is yellowish.
Eggs are laid on the underside of the leaf, usually close to a rib.
The larva makes a long contorted gallery leafmine on the food plant.
The adults fly in two generations a year: during June and again around July and August.
The larva lives on Quercus and Castanea.
