It's true that some crops like raspberries, cashews, cranberries and mangoes cannot reproduce without pollinators.

Now most pollinators that we think about are insects, but actually in the tropics, many birds and butterflies pollinate.

Through evolution, most flowers have become adapted to attract specific types of pollinators.

Although nectar is crucial for most pollinators, its evolutionary origin has received scant attention.

Flies and beetles are the original pollinators, going back to when flowering plants first appeared 130 million years ago.
