157 Heliozela hammoniella mine and cut-out on Downy Birch, Norland Bilberry Slopes, Oct. 8th 2017. The larva mines the petiole then in to the mid-rib and finally the leaf blade. It excises the blotch mine it creates before falling to the ground to pupate. It leaves behind a neat oval encompassed by a dead, brown "lasso". It was interesting to dissect the mine tracing the tunnel of frass back to the base of the petiole.
