Upstate NY USA here.

I am trying to identify the type of insect that this is:

Is this a cockroach? If so what type/sub-species might it be? If not, what other type of bug have I stumbled across here?

  • $\begingroup$ Size approximations would be helpful. It's not a cockroach by the looks of it; just a harmless beetle of some sort. $\endgroup$

This is some species of Ground Beetle (family Carabidae); the trochanter of the hind leg (just before and somewhat overlapping the femur) and the threadlike antennae helps point to that group. The book The beetles of northeastern North America by N. M. Downie and Ross H. Arnett (Sandhill Crane Press 1996; now out of print but in at least some libraries) may help with a species identification (fair warning: the keys are not profusely illustrated).
