Is it Feral or Wild bees ?

WILD - and that applies to ALL bees.  Bees have never really been domesticated. In my view the term “feral” (having returned to an untamed state from domestication) is inappropriate. Often I see the phrase "escaped unmanaged bees" where the author wants to separate bees from native wild bees.

Does it matter? I think so, as some people seem to think bees need us. They just need us to stop poisoning and removing food.
