Diagnostic
summary
- larvae feed
on the green tissue inside the leaf, leaving the transparent upper and lower
membranes (epidermis) intact.
-
young larvae enter the leaf and form serpentine mines (narrow
grey or silvery tracks) while mature
larvae form broader "blotch" mines.
-
serpentine or blotched mines which later become holes as the
mined tissues are destroyed. The lower surface of the infested leaves become
dirty with blackish frass and show silken webbings where the insect
pupates.
-
with high infestation, the leaves
become brown.
- Heavy infestation may occur during or after a prolonged dry period.
