When there’s a bumblebee colony nearby or an apiary, you will automatically see more bumblebees of this species or honey bees flying around. It’s a numbers game.

I like to call them the polar bears between the bees. This is funny, because, as I learned today, in China apparently they’re called…

In the examples I gave last week, we saw how a divergence between the flowering period of a plant and the activity period of a bee species can affect the latter. Such phenological mismatches happen when plants and pollinators react differently to rising temperatures. Phenology, if…
