1 > Leaf-miner: A
narrow linear mine, even in the finest subdivisions of the leaves
(Spencer, 1972b: 77, as matricariae ; Spencer, 1976: 478).
Very
fine corridor, upper- or lower-surface, even in the narrowest leaf
segments. The corridor may be up to 14 cm long (Sehgal, 1971a).
Generally the corridor descends towards the leaf base. Frass in
pearl chains of loose grains, hardly in strings. Pupation outside
the mine.
