I stumbled upon this video about bees. It looks a big sensational, about the end of the world, but it turned out to be actually very nice. It answers the question about what would happen if all the pollinating insects died. Not just bees but all kinds of species.

Honeybees are domestic animals, they do not occur in the wild anymore. I think there is a lot of interest about the honeybee, while actually people can manage them quite well. They are domestic and all of them are kept by a bee keeper. The other insects and the wild bees are more interesting in my option. Many other species of bees, solitary bees, humblebees and other pollinators that will pollinate our food plants.
