This is an Ivory Marked Beetle, Eburia quadrigeminata, and according to BugGuide: “hosts include a wide variety of hardwoods (oak, ash, hickory, locust, chestnut, maple, elm, beech, cherry); larvae bore in heartwood.” According to MoBugs: “Deciduous woodlands and the nearby area is their favored habitat, but they will often come to lights at night. Females deposit eggs on hardwood trees, usually in the cracks of bark. (Let me clarify here, they will only feed on dead or decaying trees, they will not harm healthy living trees…Thanks Ted for pointing out my oversight).When the larvae hatches it will eat its way into the heartwood of the tree. They feed on the wood pulp. Adults will readily come to fermented molasses bait. In large numbers these beetles could become serious pests to trees, and can cause significant damage. Because of their boring habit, and their capability of reaching the center of even the largest of trees it is not uncommon for these beetles to emerge as much as 10 to 40 years later in wood that was used to make furniture or hardwood flooring.” We suspect this individual was probably attracted to light or had some other accidental reason for appearing in your home, but we would not rule out the possibility that it might have emerged from some finished wood product or firewood stored indoors. Since today is the last day of July, and it is time for us to select a new Bug of the Month, we will be featuring your submission.
