Flowers that require pollination have developed their own signals - I think
it works something like ultraviolet reflection on petals pointing the way to
a feed. I doubt that sun-dews will be a major hazard since bees rely on
foragers returning to hives to indicate where nectar is to be found.
Carnivorous plants may snare random bees but individual bees are only a very
small part of the hive organism. I believe bees are preferentially attracted
to white flowers, then blue and yellow. Sundews do not require a great deal
of prey to sustain life - it is more supplementing soil deficiencies. I am
not even sure that they would be strong enough to trap a bee - I usually see
only very small insects being digested.
Each field bee has a foraging life of only 2 - 4 weeks in heavy nectar flow
conditions. I expect the result of bringing in hives to be mutually
beneficial to bees and carnivorous plants - more food all round.
