1 > Leaf-miner: Mine
irregularly linear, frequently following mid-rib of a leaf segment,
appearing greenish or brownish (Spencer, 1972b: 89 (fig. 298), 90; Spencer,
1976: 292, 293 (fig. 687)).
Broad,
brownish, upper-surface corridor. In most cases it makes a tour
through an entire leaf by entering each segment in turn and making
a loop up and down the main vein. Frass in grains. Pupation outside
the mine.
The brown or green mine is linear and runs alonside the midrib on several segments of a leaf. |
