spicuous. The worms descend the branches, devouring 

 the pulpy portions of the leaves upon them, and form a 

 web as they go. When they have made their growth, the 

 caterpillars descend to the ground, where, just beneath 

 the surface, they enter the pupa state; the next summer 

 they issue as pure white moths, to lay eggs for another 

 brood. The worm, or caterpillar, is of a general pale- 

 yellow color, with a broad dusky stripe along the back, 

 and a yellow stripe along each side, and they have nu- 

 merous whitish hairs. While the Fall Web-worm often 

 attacks the Apple and other fruit trees, it does not con- 

 fine itself to the orchard, but its webs may be seen in 

 autumn upon various kinds of trees, as well as on shrubs. 

 The only remedy is to destroy the web wherever it may 

 be seen; and as the worms never leave the nest, this is 

 quite sure to be effective. 



THE APPLE-WORMCODLING MOTH. 

 (Carpocapsa pomonella, Linn.) 



This is one of the most important of the insects of the 

 orchard, in view of the great loss it annually causes. 

 While all those who eat apples have seen its work, a bur- 

 rowing at the core of the fruit and an abundant deposit 

 of excrement, very few, even among fruit growers, have 

 seen the perfect insect, which is a small moth. Like 

 most of our worm insect foes, it was originally a denizen 

 of the Old World, having been introduced into this 

 country only about the beginning of the present cen- 

 tury. Twenty years ago it was unknown in Illinois; 

 and it is only within the last eight or ten years that it 

 has penetrated into Iowa. 



The Apple-worm moth makes its appearance in North 

 Illinois from the last of May to the forepart of June, and 

 a little earlier or later according to the season and the
