The tube lipped nectar bat. A pool of delicious nectar

These are nectar spurs.

It does not eat nectar.

It does not eat nectar.

So here is some nectar from my film.

The bee flew to the flower and drank the nectar.

And here is the long probosced fly that has not gotten any nectar from the mimic, because the mimic doesn't give it any nectar.

And when it takes the nectar, the flowers don't feel shortchanged.

I'm going to get the nectar and I'm going to leave.

They drink this fabulous nectar and then they're all a bit sticky.

And they're also collecting nectar and that's what makes the honey that we eat.

And they're also collecting nectar, and that's what makes the honey that we eat.

They might say, I've got a bit of nectar. Do you want to come and get it?

What the honey bee does it pollinates, takes nectar from the flower, pollinates another flower, cross pollinates.

They get paid by pollen and nectar, to move that male sperm, the pollen, from flower to flower.

And basically what the insect has to do we're in the middle of the flower it has to stick its little proboscis right into the middle of that and all the way down that nectar tube to get to the nectar.

like in the case of orchids that promise sex and nectar and give in change nothing for the transportation of the pollen.

There's a symbiotic relationship there, whether it's flies or birds or bees, they're getting something in return, and that something in return is generally nectar.

This is a plant here that insects in South Africa just love, and they've evolved with a long proboscis to get the nectar at the bottom.

And the bee has been cleverly fooled into taking the nectar, and also picking up some powder on its leg, and going off to the next blossom.

Mosquitoes actually live ... their day to day nutrition comes from nectar, from flowers in fact, in the lab, we feed ours raisins but the female needs the blood meal.

Now you can imagine that if nectar is such a valuable thing and expensive for the plant to produce and it attracts lots of pollinators, then, just as in human sex, people might start to deceive.

This orchid, known as Darwin's orchid, because it's one that he studied and made a wonderful prediction when he saw it you can see that there's a very long nectar tube that descends down from the orchid.

And if you look a little bit closer at this stigma and the stamen here, this is the style of that flower and you notice that it's got this little jelly like things that are called spurs, these are nectar spurs.

So not only has the fly not got the nectar from the mimic plant, it's also if you look very closely just at the head end, you can see that it's got a bit of pollen that it would be transmitting to another plant, if only some botanist hadn't come along and stuck it to a blue piece of card.

So we know flowers, we know fruits and vegetables, even some alfalfa in hay that the livestock for the meats that we eat, rely on pollinators, but you've got male and female parts to a plant here, and basically pollinators are attracted to plants for their nectar, and in the process, a bee will visit some flowers and pick up some pollen, or that male kind of sperm counterpart, along the way, and then travel to different flowers, and eventually an apple, in this case, will be produced.
