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.
that's a lovely photo! did you take it? I couldn't find anything on a reverse image search...
Thank you! I did! It's here in the Awwnverts community: https://lemmy.world/post/2928386 And here she is from another angle in the Beebutts community: https://lemmy.world/post/2929223
I've been carefully deadheading that bull thistle that grew in my yard this year because I don't want only bull thistle in my yard next year, but the bumble bees just freak out over it, so I don't have the heart to get rid of it while it's in bloom. It's about six feet high and very thorny.
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.
The flowers are also evolving to spread pollen to reproduce. Flowers have evolved to be bright, colorful and have pollen that bees want. Flowers are able to get there pollen spread and bees get food.

Secondary comment, still not an expert...
But even if there were no bugs on the planet, I'm pretty sure a good stiff breeze would still make pollen move...

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.
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.
Re: wasps, some orchids grow petals that look like a wasp's ass to trigger attempts at mating.
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?
I mean there is a certain amount of violence, look at how these orchid flowers grab their wasps.
Tagging the OP @SeahorseTreble come and look at this footage, it will give you a different perspective for sure.
Bro out here thinking bees are fucking farmers, fucking hell.
I mean... Ants farm Aphids. Why couldn't bees farm flowers?
First I've read "planets" rather than "plants" and got really curios what I've missed in the meantime.
