Greetings,
I'm from the Netherlands and I've got this strange thing going on. There is this single bee that keeps returning to the underside of my window and deposits this yellow powder (pollen). I can literally just open my window and scoop it all up or something (i haven't done anything yet), but it's just laying there.
I don't understand why it's just one bee. It doesn't seem like a larger queen or something.
Now I don't really want to end up with a nest here, but I feel like I should care for the bees too. What to do?
