Possibly queen carpenter ant? -
Meloe niger

I find one or two of these every spring. They look like carpenter ants that are giganticly fat. I have thought they are probably pregnant carpenter ants. Or are they something else?

bugguide says:
Pressing, rubbing, or squashing adult blister beetles may cause them to exude their hemolymph (“blood”), which contains cantharidin.
