INSECTS INJURIOUS TO THE RASPBERRY. 



ATTACKING THE EOOTE. 



Fig. 313. 



No. 174. — The Raspberry Root-borer. 



Beinbecia znarginaUj, Harris. 



This borer is quite distinct from the cane-borer, No. 176, 

 that insect being without legs in the larval state, wliile this 

 one has sixteen legs, a feature which will enable any person 

 readily to distinguish the one from the other. The rasp- 

 berry root-borer belongs to the same family of clear-winged 

 moths as the peach-borer, and there is a striking resem- 

 blance between the two species in the several stages of their 

 existence. 



Both the male and the female moth are shown in Fig. 313, 

 where a represents the male, and 6 the female. The front 

 wings are transparent, veined with 

 black or brownish, and heavily mar- 

 gined with reddish brown ; the hind 

 wings are transparent, with dark veins, 

 and both wings are fringed with dark 

 brown. The body is black, prettily 

 banded and marked with golden yel- 

 low, as in the figure. The wings, 

 when expanded, will measure from 

 three-quarters of an inch to an inch 

 across. 



The eggs are said to be depositee 

 by the female during the hot summer 

 w'eather on the leaves of the raspberry, and the young larva, 

 when hatched, finds its way from these to the stem or cane, 

 and there feeds upon the pithy substance in the interior,
