Not all bees and wasps can sting.
Wasps are the new beesAside from Meliponini, there are some other solitary bees, like miner bees, that also have very reduced stingers, but for the most part the bee species you probably encounter in daily life are capable of stinging.
But even social bees and wasps foraging far from their nests are unlikely to put their lives on the line when fleeing danger is an easier option. Stinging as defense costs energy. It’s time away from foraging or hunting, says Sadler, “and then venom, right? They use venom that they’d then have to produce [again].”
Solitary bees and wasps usually have multiple small nests where they leave their young without much ongoing parental care. Their genetic line dies with them as individuals, and so they are much more risk-averse when it comes to deploying stings. Solitary bees and wasps aren’t even particularly likely to sting to defend their own nests, says Schmidt. If their nest is threatened, they’d sooner lay new eggs in a new nest than die to protect replaceable young.
