There are tliree stiiges in the life history of the codling moth: — 

 (1.) Tlie larva or worm ; C2.) The pupa : (3.) The moth or mature insect. 

 The insect always passes the whiter in the larval condition, as a worm. 

 It sphis ahout itself in the fall a web called cocoon, to protect itself from the 

 cold, rain, other in.sects and birds. It endeavours to find, and almost always 

 succeeds in finding, some dry place to pass the winter, such as old fences, 

 boards, scal.v bark of trees, or even large clods. .\t varying times in the 

 spring, according to the season or whether it lias a warm or cool hiding place, 

 this worm changes into that peculiar brown oliject called the pupa, and from 

 this stage into the moth. Here is the first and most imiiortant point for the 

 aiiple-grower, who intends to fight the moth successfully, to understand. 

 You must know just ir7/<7! the moth appears in order to do intelligent work. 

 Therefore, prepare yourself a hrcciliny cage and confine some of the worm.s 

 in it. that you may kiioir with certainty when the moth comes out. One of 

 the simplest cages is a wide-mouthed fruit jar, and in place of a lid tie some
