Found In Oak Firewood - Hylesinus

Found In Oak Firewood - Hylesinus
Pound, Marinette County, Wisconsin, USA
August 7, 2005
Size: Tiny - like small ant
I found this in August in our basement -- there were hundreds of them. The were crawling around in some Oak firewood we recently put in the basement. Many were dead on the basement floor. I would like some help identifying this bug and wondering if it posesses any harm to my house.

Solytinae, Hylesinus aculeatus?
A "firewood beetle" that cannot survive in the house. In New Hampshire it would be Hylesinus aculeatus, probably the same in Wisconsin.

Bark beetle.
This looks more like a bark beetle of some kind. I'd check which species of Scolytinae are associated with oak and then eliminate them as suspects before looking elsewhere.

Sap Beetle?
I'm not an expert but I think its a specie of Sap Beetle There is a web site with lots of info on these Here. Whether they're a problem for your house may be addressed on the web site or maybe someone here can say. ( After looking closer at this I'm going to go out on a limb and guess it's a Glischrochilus fasciatus (Olivier))
