Dear aysia,
This is an Ivory Marked Beetle,
Eburia quadrigeminata, and late December is a very unusual time for a sighting.  Perhaps we should include additional questions on our submission form, including “When did the sighting occur?” and “Why do you want to know?” because that kind of information will help us formulate a response.  We try to make things as easy as possible for folks who are writing to us, but that doesn’t help us when we are trying to craft a response that satisfies the real reason a person wants to know: What’s That Bug?, especially with folks of few words.  Because it appears to be nestled in a paper towel, we suspect you found this Ivory Marked Beetle in your home and you want to make sure it isn’t going to do any damage, but you never clarified any of that.  The larvae of the Ivory Marked Beetle are borers that will feed on a “wide variety of hardwoods (oak, ash, hickory, locust, chestnut, maple, elm, beech, cherry); larvae bore in heartwood” according to BugGuide.  We speculate this individual might have emerged early from some firewood you brought into the house and didn’t burn immediately, or this individual might have emerged from milled lumber because BugGuide also notes it is:  “Notorious for emerging from furniture after as many as 10-40 yrs.”  You do not need to worry about Ivory Marked Beetles infesting the wooden furniture or structural wood of your home.
