The young larva mines the leaf of Crataegus, Malus, Pyrus or Sorbus, generally beside a vein. Later, it feeds externally, mainly on the upperside of the leaf. Pupation in a white, ribbed cocoon on detritus.
The adults have been observed from mid May till mid August, most common in the second half of May. They fly in the evening and later come occasionally to light.
