316 PESTS OF ORCHARD AND SMALL FRUITS 
of injury may be observed on the expanding buds, on which clusters 
of the lice are found, their work resulting in deforming the young

young fruit. 
The life histories 
of these various 
species are not the

the similarity in 
their superficial ap-

larged and natural size. Original. 
(Aphis pomt) 
passes the entire season on the apple. In the winter it is in the egg 
stage, large numbers of the small, black shining eggs often being 
found on terminal 
twigs. The first 
generations in 
summer are wing- 
less, but in later 
generations 
winged individuals 
develop. This 
species is charac- 
teristically bright 
green in color, 
with black, rather 
slender honey 
tubes. It is one 
twelfth of an inch 
long. Usually the lice observed on tender shoots and beneath curled 
terminal leaves belong to this species or to the following.
