the attached image came out of my table. we accidentally decapitated it when trying to extract it, so the image has no head, which is really tiny with two antennae. We can’t find what it is. the closest we got was a metallic beetle of some sort. it came out of cedar, if that helps, and we got the wood from a felled Hurricane Sandy tree
We are sorry for the long delay in getting back to you, but this identification has been on our back burner for several weeks now. We made a few attempts to identify the beetle, but we did not have any luck. We should have paid closer attention to your information about it emerging from cedar, a wood not normally prone to insect infestations. Today, while researching a different submission, we stumbled upon a posting in our archives of a Cedar Tree Borer, Semanotus ligneus, and it matches your image, and it has the head which distinguishes it as a Longhorn Borer in the family Cerambycidae. You can see additional images on BugGuide. When lumber containing wood boring insects is milled, the emergence time may be delayed for years.
