Longhorn Borer Pupa

Firewood bug
January 17, 2010
Hello. We received some firewood that was loaded with insect tracks, lots of bore holes and trails through the wood. Some bugs were found IN the tracks. Worried that these may be a bug that could harm the house, if we don’t burn the wood!
Thanks in advance for any help you can provide! Courtney

Longhorned Borer Pupa

Hi Courtney,
Your photo is of very low resolution, and when we enlarged it, the quality was further reduced.  We believe this is a pupa of a Longhorned Borer Beetle in the family Cerambycidae.  The family is often abbreviated as the Bycids.  Without knowing the host tree, it would be difficult to pin down a species, and some trees are host to numerous species of Borers.  A much clearer photo of a Cerambycid Pupa is posted to BugGuide.

Thanks very much for your work.  I wish our camera was better, but alas, ’tis all we have.
