This is a pretty spectacular longhorn called the red oak borer, Enaphalodes rufulus. This looks to be a female. Males have much longer antennae. They often come to lights at night. This species is becoming "troublesome" in some oak forests, especially in Arkansas and Missouri. One theory is that after logging way back when, the forests were reseeded with oaks of essentially the same age. Now those trees are getting old, stressed by drought and thin soils, and are getting decimated by these beetles as a result of their weakened state.
