A common species in Belgium.
Native
The mine differs a little bit on both food plants; in Carpinus the mine has a strong tendency to follow the veins, frass is a little bit diffuser and in generall it's shorter and a little bit wider. In Corylus the mine hasn't a strong tendency to follow the veins, it's longer and frass is narrow linear.
It pupates in a cocoon spun on detritus.
The adults fly in two generations a year in late April-May and July-August.
The larva makes a leafmine on Carpinus betulus and Corylus avellana.
