This is a really nice strong colony of bees. They're working the balsam, they're working the bramble. The Himalayan balsam though is a dead giveaway. When you see this, that's called a ghost bee. It has a white stripe down its back and that means that it's been deep inside a Himalayan balsam flower doing its work, getting the nectar, bringing it back to the hive. You can see it there transferring it over to another bee. But that stripe on its back there is the biggest giveaway. You see that on your bees, that means they've found the Himalayan balsam and they're foraging it to bring that nectar to the hive.
