I wouldn't be at all surprised to find that the sugar content of the black  
locust is not to their liking or
much less attractive or harder to work than the nectar bloom they were  
working just previous.  Also, maybe something else is blooming at same  time that 
is preferred over black locust but not a heavy flow.  I have a fabulous tulip 
poplar bloom in my immediate area nearly every  year (the trees literally drip 
tulip poplar nectar in a light wind),  but my bees ignore it in favor of holly 
which blooms at roughly the same  time...at least that is what the pollen 
analysis and very light color of the  honey indicates.
