I have multiple advanced beehives and expansion boxes above hoppers and centrifuge's, and several mason and reed bees flying around that have been released from a bee cage by shift right clicking on the hives.
They have been flying around for several in game days with pollen on them and not one has gone into a hive.
I also know that for at least 2 of them their hives dont exist anymore since i deleted them. and the rest have their hives several chunks away.

mason and reed bees are solitary bees and do not live in hives only in nests
