The Scurfy Scale 

 (Chionaspis fuvfura Fitch) 

 The scurfy scale is found principally 

 on apple, but occasionally on pear, 

 peach, cherry, currant, and gooseberry. 

 The scale of the female is small, flat, 

 whitish, and broadly oval. With these 



will be found the scales of the 

 male, which are smaller, narrow, 

 and longitudinally ridged. 



There is one generation annually. 

 Eggs are laid in the fall, beneath 

 the scale of the female, and from 

 these hatch the minute young, in
