over their feeding ground. When half grown they abandon 

 their webs and feed openly, devouring the whole leaf except 

 the larger veins. They feed only at night, during the day 

 remaining hidden in the soil. In about two weeks the cater- 

 pillars become full-grown and are then slightly over an inch 

 in length. They vary considerably in color but are usually 

 green with a broad, gray 

 or black lateral band bor- 

 dered on the upper side by 

 a narrow white line. The 

 mature caterpillars burrow 

 a short distance into the 

 soil and there in earthen 

 cells transform to yellowish 

 brown pupae a little less 

 than i inch in length. 

 The insect remains in this condition for about two 

 weeks. In California there are two or three broods a season, 

 the second being the most injurious.
