Scale = 2 mm. 
Early instars (A, B) had pale-colored heads and green bodies. 
They constructed hard tubes of silk and frass, 0.5 mm in diameter, 
on the undersides of leaves. Most tubes were initiated along major 
leaf veins, a position which may offer protection to young larvae. 
The initial tube was dense and the larva inside could not be seen 
through its wall. 
Subsequent instars extended the tube, each tube addition being 
wider and longer than previous portions. 
Larvae did not leave their tubes to feed; they reached out (Figure 
3) and scraped cells from the leaf surface. 
Commencing with instar C, larvae had dark heads and a pink 
mesothorax. The remainder of the body was green as before. 
Intermediate instars (C, D) continued construction of the hard tube, 
and also fed by scraping the leaf surface immediately in front of the 
tube opening. 
Later instars (E-G) ate whole leaf. Portions of the tube,
