A very rare
species in Belgium.
egg is laid on the upperside of Agrimonia or Aremonia. Initially
the larva makes a slender strongly contorted gallery with
interrupted linear frass
leaving distinct clear margins, later the gallery broadens and
finally ends in a irregular blotch which often absorbs the earlier
gallery. Often several mines on the same leaf.
adults fly in one generation a year during June.
