Cut Worms. 



Noctuida . 

 The general life-history of the various species of 

 cut worms has already been described on page 197. 

 These pests are especially liable to injure corn plant- 

 ed on sod land, but such damage may easily be pre- 

 vented by using the poison traps described in con- 

 nection with remedies for cabbage cutworms (p. 19 7). 

 The field to be planted should be strewn with poi- 

 soned clover or grass, or cabbage leaves, before the 

 crop is put in, although if not done then the baits 

 may be placed between the rows afterwards. 



The Garden Web-worm. 



Eurycreon rantalis. 



This insect occasionally becomes destructive over 

 a wide area, and damages a great variety of crops, 

 although corn usually suffers most. The adult is a 

 small, grayish moth (Fig. 114, /), expanding about 

 three-quarters of an inch, 



the females of which de- 

 posit their eggs upon the 

 leaves or stems of various 

 plants. Soon after hatch- 

 ing the young larvae be- 

 gin to spin a protective 

 web, which is enlarged as Fig. iw. Garden web-wom
