Hi all, I still do not believe a stinger is long enough to reach an artery. Have you ever looked at a stinger? Nor more than 3/32 of an inch. Arteries are deeper under the skin than this. Also a bee does not bury the stinger full depth. Most stingers only penetrate about 1/32 of an inch or less. I would think the neck has the shallowest artery of all.
