THE RASPBERRY LEAF-ROLLER. 
(Exartema permundana Clem.). 
This insect has received a number of other popular 
names, which indicate its food habits; it is called in southern 
New England the Hickory Exartema, because it feeds on the 
leaves of the hickory. Prof. Saunders calls it the Neat 
Strawberry Leat-roller. He says: ‘‘This pernicious little 
caterpillar appears just about the time that the strawberry 
blossoms are opening, and delights to form its protecting 
case by drawing the flowers and flower-buds tegetherinto a 
ball, and to feast upon their sub- 
stance, a peculiarity which renders 
its attacks much more injurious than 
any mere consumption of leaves 
would be. The larva is of a green 
color; with the head and upper part 
of the next segment black. When 
full grown it is about five-eighths of 
Fig, 221. — Exartema per- 
cages eaine tain eed an inch long, LST AVC Igy) active in 1ts 
habits, and wriggles itself quickly 
out of its hiding place when disturbed. Late in June or 
early in July it changes to a brown chrysalis, from which 
in a few days the perfect insect escapes. 
“The moth which is shown magnified in Fig. 221, has 
its fore-wings yellowish or greenish-brown, varying much in 
shade of color, with irregular lighter markings crossing the 
wings obliquely; the hind-wings are ashy-brown. 
“The caterpillar is very destructive in some districts, and 
feeds upon the wild strawberries as well as on the culti- 
’ 
vated varieties.’
