Found this bug on a fence post out in the woods.
It's called a Wheel bug, this one is in the nymph stage.
They are predatory insects, eating "pest" bugs, like aphids.
Apparently, they are not aggressive, however if bothered they will stab you with their long hypodermic-like beak. The "bite" is known to pack quite a punch.
Since they are related to stink bugs, they too can be odorous.
