234 GRAPHOLITHIDS. 
The young caterpillars injure the berries early in July, 
when the infested fruit shows a discolored spot where the 
larva has entered. When we open the berry we generally 
find in the pulp a long and thin larva of a whitish-green 
color. Besides feeding on the pulp it sometimes eats por- 
tions of the seeds, and if the contents of a single berry are 
not sufficient two or more are drawn together by means of 
silk, mixed with castings. Such injured berries begin to 
appear while the fruit is young and green, but they increase 
in numbers as they ripen. Infested berries resemble very 
much those that are afflicted by a disease called the Black 
Rot. The young larva is about an eighth of an inch long, 
has a black head and a blackish cervical-shield; its body is

dull whitish or yellowish-green. It is always very active 
and is apt to wriggle out of the grape and escape. When 
full grown it is about one-third of an inch long, and is now 
olive-green or dark-brown. At this time it abandons the 
berry, and now cuts out of the grape-leaf a little flap, which 
it folds over and fastens with silk, thus forming a small 
oblong case, in which it changes to a yellow or yellowish- 
brown pupa. Sometimes the larva simply rolls over a piece 
of the edge of a leaf and thus forms a retreat, which it lines 
with silk. The moth measures with expanded wings nearly
