Females lay their eggs individually on margins and teeth of the leaf. The remnant of the dark eggshell can be seen in the whole vegetation season. The mine is an irregular blotch mine. The faeces can be found as long threads in it. The larva is light grey with porcelain like shine. The fully grown larva pupates within the mine. The adult is 3-3,5 mm long, black with bronzed shine. Light coloured hair bands can be seen on the wing cases. Widespread and common in Both Europe and Hungary.
