presence of a prolonged beak or snout. It is about one-fifth of an 

 inch long ; color, mixed black, brown and white, with darker shades 

 predominating. Several humps occur on its back, giving the dorsal 

 surface a roughened appearance and affording it some protection 

 on account of its resemblance to the bark on which it rests. The 

 curved snout is about one-third the length of the body (Fig. 127). 



FIG. 125. First spraying for codling moth forcing the liquid into calyx cup. Note 

 that there are two cavities in the calyx cup, an upper and a lower (1 and 2 in b), separated 

 by stamen bars (61). A few days after the petals fall, while the apples are still erect, these 

 bars wither and separate (c 1), allowing the poisoned liquid to enter the lower cavity of the 

 calyx, (a after Slingerland, remaining figure after Ball.) 



Life History. This beetle is sometimes called the "Little 

 Turk," because the female, when the apples are no larger than peas, 

 punctures them with her beak, introducing an egg into the puncture, 

 and then cutting a crescent in the fruit at one side of the egg, pre- 

 venting, it is believed, the growth of the tissue and the consequent 

 crushing of the egg by so doing. This act on the part of the female 

 beetle causes a distorted growth and the fruit would rank as imperfect. 



The beetles leave their hibernating quarters in the spring, before
