The insect depicted is the ivory marked beetle borer, or a related species. The larvae of long-horned (-= long antennae) beetles feed on hardwood, such as oaks, maple, hickory, and ash. The ivory marked beetle is active from April to September.
The larvae live a tough life, but they are hardy. Beetle larvae have been known to survive tree cutting, milling, finishing and varnishing to emerge as adults from finished wood products. The conditions inside a piece of furniture are even harsher for the beetle larvae than a typical log. The harsh conditions may extend development time.
In 1995, a pest control company reported receiving a call from a family in Florida who heard a gnawing sound from inside a chair. The pest control technician investigated and pulled an Ivory Marked Borer out of the chair. This was 5 years after the chair had been purchased!
These beetles don't pose any risk to humans. They don't bite or sting, nor feed on anything that would affect humans.
I hope this helps,
