Random trivia I learned from a visit to a fruit farm a few weeks back: Fruit farmers much prefer bumble bees to honey bees because they're much better fruit tree pollinators - bumble bees start much earlier in the day than honey bees (e.g. 07.30 vs 12.30), will work at much lower temperatures, and will pollinate 6 flowers in the time a honey bee takes to do 1 (because the honey bees tend to stick around longer on a flower to get more nectar out).
