1 > Leaf-miner: A large, brownish blotch, with conspicuous feeding lines. Pupation
external (Spencer, 1972b:
62 (fig. 205), 63; Spencer, 1976:
308, 309 (fig. 557)).
Large,
brown, upper-surface blotch with conspicuous primary and secondary
feeding lines. The feeding lines are the more apparent because the
semiliquid frass adheres to them. Pupation outside the mine; exit
slit in the upper epidermis.
A short broad gallery, normally at the margin, leading to a blotch with obvious feeding lines in whorls. Mines go brown. |
