I think John got it - the Banded Ash Borer, a native borer common to 
most of the US as well as eastern Canada.

Per a flyer from Utah State: "Hosts of the banded ash borer include ash, 
hickory, elm, mesquite and, occasionally, white oak. This species 
generally will not attack a healthy tree, but is attracted to dead, 
dying, diseased or stressed trees."

I'll let them do their thing - besides, the bluebirds seem to find them 
tasty :-)

Thanks all for the help.
