INSECTS INJURIOUS TO THE RASPBERRY'. 



ATTAOKINQ THE PEUIT. 



No. 184. — The Raspberry Geometer. 



Si/nchlora rubimraria (Riley). 



The larva of this pretty moth feeds chiefly on the fruit cf 

 the raspberry j it is said that it occasionally feeds also on the 

 leuf. Fig. 330 shows the larva, of natural size, on the fruit 



at a ; b, an enlarged 

 view of one of the 

 segments of its 

 body, showing the 

 lairs with which it 

 s adorned. The 



moth, of the nat- 

 ural size, is seen at 

 c, while at d an en- 

 larged outline is 

 given of one pair 

 of the wings. 



The larva reaches 

 maturity about the 

 time of the ripening 

 of the raspberry, when it is about three-quarters of an inch 

 long, of a yellowish-gray color, each segment being furnished 

 with several short prickles. It has the habit of disguising 

 itself by attaching to its thorny projections tiny bits of vege- 

 table matter, such as the anthers of flowers, bits of leaves, 

 etc., and by this means it often escapes detection. 



When full grown, the larva forms a slight cocoon, within 

 which it changes to a chrysalis of a pale-yellow color, with 

 barker lines and spots, which in a few days produces the 

 perfect insect. 



The wings of the raoth are of a delicate pale-green color, 

 crossed by two lines of a lighter shade, and, when expanded.
