Expert Response
The insect in the photo is a brown prionid (Orthosoma brunneum), which is a species of longhorned beetle. I'm not sure if the specimen in the photo is a female or male.
Brown prionids
are a native species that occur throughout eastern North America. They
are reasonably common around moist woodlands as the larvae feed on roots
and wood in contact with wet ground. The adults sometimes come to traps
baited with sugar, so presumably
feed on sap or rotting fruit as adults. They're not pests as the larvae
only feed on dead wood.
