Life History. 
The beetle first appears on the wing in the spring about the first Aveek 
in May at elevations of 5,000 to 5,500 feet. 
It tunnels into the wood of newly dead or dying Ban oaks for egg lay- 
ing purposes. The insect bores straight through the bark and into the 
sap wood and then turns to one side or the other and carries its gallery 
right down into the heart wood at an angle. These beetles lay the eggs 
of the first generation of the year. 
This is all that is at present known on the life history of this beetle. 
It will not attack dry wood. The holes drilled in the wood are circular in 
section.
