European Com Borer 



Pyrausta nubilalis Hubn. 

 Cltunp of barnyard grass, Echinochloa crus-gallil 

 infested by borers. Note the two cateipillars in the sHt portions of 

 the stem. The abiHty of this insect to maintain itself on various 

 weeds, a habit now limited to eastern Massachusetts, greatly 

 complicates the problem.
