This is a Longhorned Borer Beetle in the family Cerambycidae, and larvae from this family bore in wood. We are consulting with Eric Eaton to see if he agrees with us, but we believe we have correctly identified your beetle as Pronocera collaris thanks to this BugGuide image. According to Arthur V. Evans in his book Beetles of Eastern North America: “Larva develops in spruce (Picea) and pine (Pinus). Adults active in summer on flowers.” Do you have a wood pile of pine or spruce or have you recently brought a pine or spruce piece of new furniture into your home? The larvae might have been developing in the wooden item and then emerged inside your home. Our editorial staff grew up in Campbell on the east side of Youngstown and we still visit several times a year.
