1a > Leaf-miner: A
narrow contorted gallery leading to a whitish blotch with scattered
frass centrally. The early gallery can merge with the blotch and
there are often several to a leaf. The larva begins by making a full depth corridor,
erratic in width and course; frass black, in an irregular central
line. Later the larva makes a blotch, with frass in irregular clouds.
This blotch can be a continuation of the corridor, but may just
as well be on a different leaf. Often several mines in a leaf; in
such cases the entire leaf me be mined out. Mines white at first,
turning brown later. The larva lies venter-upwards in the mine.
Pupation external. Occasionally in a mined leaf or in a cocoon between the leaves or
on the leaves. |

1b > Leaf-miner: A

red at the edges. This leads to a yellowish blotch containing dispersed
frass. |
