Life cycle
Eggs
Laid on either side of a leaf of one of the smooth-leaved willows in May–June or August–September.[1]
Larva
The larva is amber-yellow with a brown head and has a faint chain of pear-shaped dark ventral spots.[2]
The larvae feed on Salix alba, S. babylonica, Salix x sepulcralis 'Chrysocoma', Salix x fragilis, S. pentandra, S. triandra and S. viminalis. They mine the leaves of their host plant feeding inside a widening corridor. Its course is variable, but generally it contains several long nearly straight segments.[3]
