From my understanding: I get that for honeybees, they need the nectar to make honey (their energy food source) and the pollen is an additional, essential food source for them which contains protein. They collect both nectar and pollen from flowers. For other pollinators like wasps, they don’t make honey but they still need to eat nectar and pollen which they collect from flowers. Though these pollinators benefit (survive/thrive) by collecting nectar and pollen from flowers, they also help plants to reproduce by carrying pollen between them and depositing it.

But why do they transfer pollen to other flowering plants? Of course this allows certain plants to reproduce, but that doesn’t explain why these pollinators care about helping plants reproduce. Are they little plant farmers who actually realise that transferring pollen and therefore making more plants, would benefit them? That would seem to demonstrate pretty high-level intelligence and foresight, planning wouldn’t it? Or is it just incidental that they’re going between flowers collecting nectar and pollen and happen to drop some pollen from previous flowers along the way?

I really struggled to find any information on the “WHY” of what bees are doing, from their own psychology point of view.

    Bees make excellent pollinators because most of their life is spent collecting pollen, a source of protein that they feed to their developing offspring. When a bee lands on a flower, the hairs all over the bees’ body attract pollen grains through electrostatic forces.

    Basically plants have coevolved with these pollinating insects. Plants that can develop the best pollen that sticks to these insects are able to reproduce more successfully. While bees, as the example, are collecting it as there food. Bees are not “helping” the plant knowingly, its more of the plant is hitching a ride.

      So, the plants found a way to hijack the bees’ journey by putting some extra pollen on them to take to other flowers, since they’re already there taking pollen anyway? That’s awesome.

      When a bee lands on a flower, the hairs all over the bees’ body attract pollen grains through electrostatic forces.

      Were those hairs evolutionarily selected for because they help the bees spread their food source, or do they serve another purpose?

        Ha I was writing another comment on this thread when this got posted, but I just feel like it’s important, relevant to that, to say that the hairs didn’t evolve FOR any specific purpose.

          Well said. Evolution doesn’t have a goal. I ran into the difficulty when teaching is that students tended to assign purpose to mutations that are currently beneficial.

        Possibly when furrier bees evolved, it could be that the fur was protecting them from harsh weather conditions and allowing them to fly further and making it to more flowers. The fur builds electrostatic forces as the bee went along with its day. Serving another beneficail purpose by attracting more pollen to stick onto their bodies. The bees also use the fur to wipe pollen from their eyes and off their legs.

        Essentially furrier bees were more successful at feeding their offspring than non-fur bees. Which was selecting for even furrier bees in the following generations continuing to the furry honeybees we see today.

          I would point out that the furry bees transfer more pollen, which leads to more of the plants and ultimately flowers that the bee likes.

          Therefore the furry bees have an advantage by increasing their own food supply.

    Bees are messy. When they go to the flower, it gets all over them.

    The flowers are designed such that the pollen does this…. Because the flowers that do spread better. The bees are just there to get food, but while they’re going about getting food, they’re making an awful mess, and the flowers benefit.

    They aren’t farming, they’re foraging, and have evolved symbiotic relationships through evolution. The plants get a benefit by getting pollinated, the bees get a benefit by having more flowers to feed on.

    Since they need pollen, bees who developed those little hairs are/were able to out-compete bees who didn’t have them. They’re able to carry a lot more pollen and incidentally transfer it, spreading it around, so the new bees are better pollinators. That helps plants produce a lot more flowers, so it’s truly a symbiotic relationship- one would not exist without the other. Since wasps are omnivores, the evolutionary pressure to specialize isn’t as strong.

    IIrc, there are some wasps who have specialized relationships with certain plants and flowers too, driven by evolution- the flowers depend on the wasps, and the wasps depend on the flowers.

    This is funny, and really speaks to a fundamental issue we have during education as to assigning agency for what amount to"random" events.

    OP is presumably educated and intelligent, and the takeaway they had was that bees “are pollinators” which is true with regard to our interest in them, but definitely implies agency that they are intentionally pollinating, which (I am pretty sure) isn’t true.

    It feels like the same question that gets asked in a million different ways of “why did XYZ evolve that way when ABCD?” (Because evolution is random and tends toward selecting for energy conservation. Not to “achieve” some specific goal.)

    Disclaimer: I am not an expert.

    With that said, I believe it’s mostly an accidental transfer as the pollen is basically a dust that easily carries on flying bugs legs.

    If I’m wrong and experts know a more scientific answer, feel free to downvote me into oblivion.

      Am not an expert either and I agree with you : like he guessed it is incidental.

    i remember learning about how (some?) flowers are shaped to sprinkle pollen on the back of the insect. They may not need to “consciously” carry pollen, it spreads, it’s on their body.

    nectar is supplied in small doses to keep the insect (or the bird) working

    insects or birds are just trying to get more nectar (?)

      You’re saying is that flowers are nature’s pimp. That’s cool, I guess.

      As long as flowers don’t start smacking a bee for not collecting. Feel me?

    First I’ve read “planets” rather than “plants” and got really curios what I’ve missed in the meantime.
