Dear P,
This is a Longhorned Borer Beetle in the family Cerambycidae, and what you have mistaken for a stinger is the ovipositor, and organ that is used by the female when laying eggs.  We did a web search using the key words “Cerambycidae, ovipositor, New Jersey” and we were led to Green Art and an image of
Graphisurus fasciatus and the information that it:  “is well camouflaged when moving about on tree bark. The best way to find it is near lights in the night. The larvae are boring into hardwood. Note the large ovipositor of the females.”  We verified the identification on BugGuide.
