Honey bees are the masters of phenological plasticity.  We just moved some colonies from Colorado where first pollen from Siberian elm was just starting to Tennessee where the progression of bloom is much more advanced and started a good six weeks ago.  An hour or so after first foraging weather all colonies were bringing in large pollen pellets.

The question is how adaptable are other species, particularly those who overwinter in the form of immature stages.  If their development is temperature dependent, they may do ok.  And some are already pretty adaptable, as in some desert species skipping a year in emergence when humidity is low.
