The Currant-stem Girdler 

 Janus integer Norton 



In the Northern states and Canada currant bushes are often 

 injured by a sawfly, which, after depositing her eggs in a cane, 

 girdles the tip, caus- 

 ing it to wilt and 

 drop. It is a na- 

 tive insect which 

 probably fed origi- 

 nally on the wild 

 currant, but did 

 not attract atten- 

 tion as an enemy 

 of the cultivated 

 varieties until 

 about 1888. 



The sawflies 

 emerge from the 

 middle to the last 

 of May in New 

 York ; both sexes 

 have shining black 

 bodies and light 

 brownish-yellow 

 legs (Fig. 316). In 

 the male nearly all 

 of the abdomen is 

 of a broAVTiish-yei-
