I killed a wasp with a shoe in the house today and noticed that despite the wasp being dead, its stinger part is still moving. How and why is that?

Answer 1

Death twitches. Most animals, humans included, will continue to twitch even after death. This is caused by the body’s muscles expanding and contracting on their own, adjusting to the built up tension from normal use as well as the blood and energy settling. It usually stops after a minute or two.
