mine

Orange brown to rust-coloured lower-surface blotch, mostly near the midrib. Towards the end of the mining activity silk is deposited in the mine; this causes the mine to contract, folding the leaf over the mine. Frass packed in a corner of the mine. After some time the larva vacates the mine and lives free then in a leaf tip that has been rolled downwards and fixed with silk. Two of such cones are made and eaten out from the inside. Pupation in a membranous, shining cocoon at the underside of a leaf.
