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. It thought it would get some.

Diet In the wild, lorikeets feed on nectar and pollen from plants and flowers.

The most common dietary item was nectar from flowers of the Bertram palm ( Eugeissona tristis ).

At least 24 native species from 17 plant families are targeted for nectar or pollen consumption.

Most sunbirds feed largely on nectar, but also take insects and spiders, especially when feeding young.

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.

Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals.

75 women's groups have received training in fruit processing and conservation (juicing, drying, syrup, nectar, pickling, preserves).

Adults Most adults feed on nectar, although a few tropical species feed on eye secretions, and the death's head hawkmoth steals honey from bees.

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.

But some plants are manipulating animals, like in the case of orchids that promise sex and nectar and give in change nothing for the transportation of the pollen.

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.

Sunbirds and spiderhunters Order PasseriformesFamily NectariniidaeThe sunbirds and spiderhunters are very small passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young.

A species having a proboscis two or three inches longer could reach the nectar in the largest flowers of Angræcum sesquipedale , whose nectaries vary in length from ten to fourteen inches.

And that bee, no doubt, assumed that it had decided, I'm going for that apple tree, I'm going for that blossom, I'm going to get the nectar and I'm going to leave.

A more detailed study of another Sunda slow loris population in 2002 and 2003 showed different dietary proportions, consisting of 43.3 gum, 31.7 nectar, 22.5 fruit, and just 2.5 arthropods and other animal prey.

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.

So this, for example, when you see bees flying around these little plants, and they're collecting pollen, those pollen grains that they're collecting, they pack into their legs and they take it back to the hive, and that's what makes the beehive, the wax in the beehive. And they're also collecting nectar, and that's what makes the honey that we eat.

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.

The petal of that flower looks like that, so the ant is kind of crawling over these objects, 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 these little these are like little jelly like things that are what are called spurs. These are nectar spurs.
