Xyleborus ferrugineus

Xyleborus ferrugineus
Parkwood, Durham County, North Carolina, USA
September 16, 2008
Size: 3 mm
This tiny (3 mm body length) bark beetle came to a lighted sheet. I have several views, as it was hard to get much of it in focus at once, and I don't know what might be important for ID.

(Thanks, Vasili and John. You beetle folks are amazing!)

thanx again, John
Moved from Xyleborus.

X. ferrugineus
At that location, size, and with that declivity: X. ferrugineus. X. celsus has an additional pair of larger tubercles atop the declivity (which is also steeper in celsus) which may be reduced, but here seem typical of ferrugineus.

Moved from Bark and Ambrosia Beetles. Thanks folks, I'm moving this to genus Xyleborus.


Bark beetle
This is a bark beetle (Curculionidae:Scolytinae). Can't place it off the top of my head.

looks an awful lot like Xyleborus celsus on your pix, Brad

Now that you mention it, this does like a Xyleborus sp. X. celsus is described as 3.6 to 4.5 mm, which would make this a little small. There are numerous other species of this genus and I am not familiar with them, so I can't make a species call. Haven't looked at any scolytids in awhile, which doesn't help either. :)

Thanks, Brad, I realized that just after I posted it.
