Three large bumble bees on daffodils in my garden
No interactions present.
I cannot comment on the ID, but you do need to change the spelling to lucorum. :)

Thank you for spell check, have revised
It does seem to have the lighter yellow bands characteristic of B lucorum, as well as the pure white tail that distinguishes queens (though not workers) from terrestris.
Thank you. It's the earliest bumble bee I've ever observed
