Codling Moth; Apple Worm (Carpocapsa pomonclla, 

 Linn.). — The adult is a small brown moth, which flies 

 generally at night, and deposits her eggs singly on the 

 surface of young fruit just after the flower falls. When 



these eggs hatch 

 the young worm 

 cuts its way into 

 the apple, usu- 

 ally at the blos- 

 som end, and re- 

 mains here feed- 

 ing until full 

 grown, w h i c li 

 occurs within a 

 few days. The 

 worm then finds 

 its way out, de- 

 scends to the 

 ground by a web 

 or otherwis e, 

 and passes into 

 the pupa state 

 under the pro- 

 jections of the 

 bark at the base 

 of the tree. In 

 two or three 

 weeks another 

 brood of moths 

 is formed, and 

 other apples are 

 attacked in the same manner. The larvae mature about 

 the time in autumn when the ripe apples are gathered.
