Stinger Close-Up

This close-up photo of the stinger of a bumblebee is, to some people who are allergic to stings, a very big threat to their health.  The stinger contains a toxin (which is the drop in the picture) that will only irritate most people, but will make those who are allergic swell up and possibly die.  The stinger falls out after the sting, and the bee dies soon after.
