Don't know where to post this so I've posted it here.
I just came across this excellent Russian nature video on beekeeping on YouTube. Superb footage of various cell activity that's impossible to spot or rarely seen: cut away cell showing nurse bees feeding royal jelly to larvae, laying queens, fighting queens, mating queens, tons of egg shots. And more.
A bit long at 17 minutes, and starts out slow - but stay with it! It's in Russian so you can practice your second language skills! :-DЧтобы пчёл стало больше
