THE APPLE LYONETIA. 
(Lyonetia saccatella Pack.). 
This is a very minute and beautiful moth, measuring 
scarcely one-fifth of an inch across the expanded wings. It 
is not common, but some are found in early summer. Its 
wings are of a light slate-gray color on the basal half, while 
the outer half is bright orange, enclosing two white bands, 
one arising on the front edge, the other on the inner margin, 
both nearly meeting in the middle of the wing; these white 
bands are margined externally with black; there is also a

conspicuous black spot near the fringe, from which arises a 
pencil of black hairs. 
According to Saunders the small flattened and green 
larva feeds on apple leaves; it constructs from the skin of 
the leaf an oval and flattened case which forms its house. — 
This case is open at each end, and is drawn about by the 
insect as it moves from place to place. When the insect 
reaches its full size it attaches this case or bag to the bark 
of the tree on which it had been feeding, transforms to a 
pupa, in which condition it passes the winter, giving forth 
the moth in the following spring. The insect is shown in 
Fig. 234.
