BuPRESTiDAE. The Flat-headed or Metallic Wood-borers 



The larvae live beneath the bark of trees which are just 

 beginning to decay and are usually the first to attack a tree 

 that in some way has lost its vitality. They are best taken on 

 stumps, logs, and stacks of cord wood, in open places where 

 they repair to sun themselves, especially in the morning. 

 Later in the season the best method is beating isolated trees.
