egg-attaehment larva mines directly into leaf and courses outwards towards 
circumference in more or less indirect manner in region between two of the 
coarser veins; having reached outer margin, mine follows approximately 
the serrated edge of leaf towards tip of midrib, and, crossing this, continues 
along margin for some distance, finally turning inwards towards centre 
of leaf; about this time larva is full-grown, and emerges from mine by 
cutting small slit in roof of gallery near termination. Latter third of mine 
generally somewhat vermiform, and may be so coiled upon itself as to form 
small blotch.
