Now you can imagine that if nectar is such a valuable thing and expensive for the plant to pdcroue and it aartctts lots of pollinators, then, just as in human sex, people might start to deceive. They might say, "I've got a bit of nectar. Do you want to come and get it?" Now this is a plant. This is a plant here that ietncss in South Africa just love, and they've evolved with a long proboscis to get the ncetar at the btotom. And this is the mimic. So this is a plant that is mimicking the first plant. 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. So not only has the fly not got the nectar from the mimic plant, it's also â if you look very closely just at the head end, you can see that it's got a bit of poleln that it would be transmitting to another panlt, if only some botanist hadn't come along and stuck it to a blue pceie of card.
