Pretty sure I see many bees on Magnolias.

Right, the whole point of bees as insect pollinators (reflecting that they are recent evolutionary line) is that they are by a healthy margin the most intelligent arthropod. They will inspect then successfully pollinate anything floral over a wide geographic range. Most insect pollinators are instinctually tied to certain species/families.

  • You mean honeybees? Because there are lots of other (wild) bee species that are very specialized. And they also contradict most of the other things we think we know about bees: they are usually solitary, and they rarely sting (honeybees only do that to protect the hive).

    Maybe it's the other way around: humans selected honeybees to "domesticate" because of their versatility (and of course the fact that they produced honey)?

    • Around my location (southern brazil) there are hundreds of species of stingless bees, living in colonies. Many (most?) produce honey too. I don't dispute that there are also lots of solitary bees. Bees are wonderful and way more diverse than people usually think.

  • Thanks, I never thought about bees like that. They certainly can use many types of flowers, as evidenced by various sorts of honey. Nitpick: some spiders are pretty darn intelligent and even seem to dream when they sleep, apparently.

      Note there are various species who're oligolectic meaning they only collect pollen and nectar - and hence pollinate only - a single family or sometimes even single species of plants. Moreover they are usually also better at pollinating than more generalistic species especially honeybees.

My magnolia is the only thing that seems to attract honeybees, which I rarely see otherwise. The article doesn't seem to justify the "not bees" part, though. I'd imagine bees can pollinate them too.
