 larvae." 



John, looking at the larvae Frank had in his hand, 

 said : "Those are not 

 the same kind that 

 work in my corn 



during the Summer. FIG. 66. "In summer and early fall 



They look different." they are white dotted with black '" 



Frank explained to him, "In summer and early 

 fall they are white, dotted with black, but when 

 winter comes they change to a cream yellow color, 



and this leads some people 

 to believe that they are 

 different caterpillars." 



"I want to know how 

 to kill them," John said. 

 " We ought to do as they 

 do in the Whitney sec- 

 tion," said Frank. "All 

 the farmers around there 

 destroy the corn stubble 

 in the fall. They never 

 allow them to stay in the fields over winter because 

 they say that they breed windfalls." 



"How do they destroy them, do you know?" 

 John asked. 



"There are several ways," Frank answered.

 comes they change to a cream 

 yellow."
