Corn-Ear Worm; Boll Worm (Heliothis armigera, 

 Hbn.). — This is the well-known cotton-boll worm, and the 



damage it com- 

 mits in all sec- 

 tions of the

 estimated. The 

 adult is a moth 

 varying in color 

 from yellowish 

 gray to a dark 

 yellow, and on 

 the outer wings 

 is a broad band, 

 dark on the out- 

 er margins, with 

 a white spot on 

 the inside. When 

 the wings are 

 spread the insect 

 is from one and 

 a half to two 

 inches from tip 

 to tip. The worm is about one inch long, and it trans- 

 forms into the pupa below the surface of the ground. 



Plants Injured. — Cotton bolls, corn, tomatoes, squashes, 

 tobacco, peas, beans, and potatoes.
