1 > Leaf-miner: Initially
the larva mines a basal leaf, subsequently feeding in flower buds
(which turn yellow), opened flowers and foliage.
Full depth irregular blotch that may occupy an entire leaf. Frass

mine until shortly before pupation, others leave the mine in an
early stage and feed externally on the flower buds and developing
fruits. |
