2012 (CHF): Formerly just known from the south of VC63, this species has been found further north in the county and there have also been records in Durham. Most easily found as larval mines. The larva initially mines the petiole of an aspen leaf forming a small swollen gall. It then moves to the leaf itself where it forms an elongate blotch between the midrib and the first lateral vein giving rise to a green "island" which can be very distinctive as the leaf turns brown in the autumn.
