This book is not a treatise on insect pests and diseases 

 of vegetable-garden plants; yet condensed advice on the 

 procedure in combating them is given with each of the 

 vegetables in the regular sequence. 



But some insects and similar animals are general 

 marauders. They attack several or many kinds of plants, 

 and therefore cannot be discussed under the particular 

 crops without too much repetition. They are discussed 

 here (by Crosby and Leonard, for this publication). 



Cutworms and army-worms. 



Cutworms are smooth, nearly naked caterpillars, 1 to 2 

 inches long, usually dull colored and indistinctly marked 

 with spots and stripes. Many species have the habit of 

 cutting off young plants at the surface of the ground or 

 just above it. They feed mostly at night and in the day 

 remain hidden away under stones or rubbish or in the 

 ground. The adults are dull-colored rather heavy-bodied 

 moths. More than a score of species has been recorded as 

 pests of vegetables. Under certain circumstances almost 

 any cutworm may become so abundant that it is forced to 

 migrate for food and thus assume the army-worm habit.
