@seekingwolf I didn’t know this stuff either! This site I used as a source seems to be pretty much a personal website with a lot of information but not many sources for what the author claims, but it’s still interesting reading material.
Other info on bee stings, taken from the same site:
Male bumblebees cannot sting as they do not have a sting. In males the part of the body that becomes the sting in females becomes the genital capsule in males, so is used in mating.
The reason a honey bee dies after she has stung a human is that the barbs in her sting and our relatively elastic skin prevent her pulling the sting out. Eventually she will either be swatted to death by whomever she has stung, or she will pull so much that the sting, poison sac and part of her abdominal contents will be pulled out of her body and left hanging and she will fly off to die. If the sting and poison sac are left behind hanging out of your skin the muscles will probably still be attached to the poison sac and will still pump poison for a while, so you should pull the sting out. Some say it is best to pull, other say you should use a downwards brushing motion.
It is believed that the sting evolved to be used against other insects who do not have elastic skin, so the sting could easily be pulled out. It is only relatively recently that mammals have become bee predators, so the honey bee sting will evolve to have smaller, then no barbs. However this does not explain the smooth bumblebee sting, and bumblebees are usually thought as less “advanced” than honey bees. Also it is not the survival of the individual worker that is important in a hive or nest, but the survival of the new queens and males, as only they will go on to breed.
