spinach, celery, and peas. The body is yellow, with a black stripe down 

 the back, and another down each side. The head is red. There are two 

 generations, the first feeding in early summer and the second in the fall. 

 The species hibernates as a pupa. Hand picking is the usual remedy, 

 but they may be poisoned by liberal doses of arsenate of lead or Paris 

 green. 



The Striped Garden Caterpillar {Mamestra legitima Grote) 



This species closely resembles the related zebra-caterpillar. It 

 may be distinguished from the other by its darker color and the fact 

 that the lateral stripes are divided into two portions, the upper lighter 

 than the lower. The feeding habits, life round, and means of control 

 are the same as for the zebra-caterpillar.
