Mentioned for the first time in Belgium (LG) in 2016.
The egg is deposited on the underside of the leaf usually close to a vein.
The mine of this species is very characteristic, the initial gallery is circling around the egg-site before making a irregular gallery with a interrupted frass line. The leaf turns red in the surroundings of the mine.

The cocoon is white.
There are probably two generation a year in Belgium.
