Dear sir or madam,

I recently noticed this territorial behaviour by a bee. It patrols an area between 3 sets of campanulas and attacks other bees which are pollinating a flowering marjoram plant which is next to a clump of campanulas. Is this usual behaviour ? I attach a link to a video which I took.

Yes, solitary bees are known to guard their patch of flowers from interlopers.
