Fig. 130. Prionus laticollis, larva, pupa and adult. 



PRIONUS Geoff. 



P. laticollis Dm. Throughout the State, July and August. The larva 

 lives in the roots of many trees and shrubs, including orchard trees 

 and small fruits. On grape and blackberry it is sometimes injurious, 

 causing less damage to the former than the latter. The larva re- 

 quires three years to reach its full growth; and when it works in the 

 crown of the blackberry causes so much injury that the removal of 

 the affected portion and the destruction of the borer is the only 

 remedy. 



P. pocularis Dalm. Throughout the pine barrens in July and August; 

 the larva often common in decaying pine logs.
