Since this is Science Memes, I'm feeling emboldened to geek out a bit.

In my part of North America, there are a lot of pollinators besides bees "sexing up" the apple trees. I'm guessing it's that way in many other parts of the world, too.

On the coolest days, you might not see any bees at all, but the flower flies (aka hover flies) will still go for it. On the warmest days, bees may even be in the minority of pollinators. I see all kinds of different fly species, a multitude of different wasps, many types of beetles, and sometimes even moths and butterflies -- weather depending. Plus, even that time of year, there are often other bee species which are active besides just the invasive non-native honey bees.
