They can live without their heads, in fact, they can go on living for two weeks without their heads. Firstly, because cockroaches don’t bleed a lot like a human.

Even though a bee might be dead it can still sting you, not in the way that you think, dead bees obviously can’t go flying around and actively sting you.
