mine, lighted from behind, with larva


Upper-surface blotch. The inner wall is lined with much silk, giving the mine a white colour. The silk also causes the mine to contract, pulling the leaf margins upwards; the mine can be almost completely hidden from view in this way. All frass is ejected from the mine. Pupation within the mine.
