Trivia part deux:

Bee stings are barbed and, unless the bee takes care removing the
ovipositor from your flesh, it will usually rip out it's entrails.
Bees are reluctant to use their stings.

Wasps are also stingers but are not barbed therefore they are much
more ready to sting.

Hoverflies, which resemble wasps even unto a pointy but stingless
abdomen, do not sting. Can anyone tell me how I can distinguish
(safely) between a wasp and a hoverfly?
