I always appreciate the work of nature's cleaning crews--this carrion beetle on our deck must have been busy nearby; he didn't stay long. He's of the Family Silphidae,
Necrophilia americana, as near as I could tell.
This species can have ivory, yellow, orange or red on the pronotum (though usually yellow), with the black spot. Amazing creatures, they can find dead animals to feed on from a mile and a half away with powerful olfactory nerves. I couldn't smell a thing (happily!)
