524 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



The moth is black with white spots on the wings, and bands across 

 the abdomen, as shown in Fig. 376. The larva is about an inch 

 long, of a greenish-white color, with head and prothoracic shield 

 light brown, and with brown spots on the sides of the first two 

 thoracic segments. 



Life History. " There are two broods each year in the more 

 Northern States and three or possibly more in the South. The 

 insect winters in the pupal stage in the folded and fallen leaves, 

 the moths appearing in the spring shortly after the foliage puts

 on the vine. Upon hatching, the young larvae attack the 

 foliage, folding the leaves as stated. Mr. Johnson has observed 

 that the larvae of the first* brood may attack bunches of grape 

 blossoms and young fruit in a way similar to the grape-berry 

 moth. In three or four weeks the larvae are full grown and 

 transform to pupae within the folded leaves, moths emerging 

 eight or ten days later. By midsummer and fall the insects 

 become quite abundant, and in badly infested vineyards the 

 folded leaves are everywhere in evidence and are quite con-
