Does anybody know if sugar water has a scent?  Bees have little 
problem informing other bees about its location during bee-lining, 
open feeding etc.

I don't have a set mind on the dance language issue but I think bees 
must use at least one more mode of communication besides odor and 
taste.  I assume scouts don't bring scents of several potential nest 
sites back to the swarm so how else do they share this information.  

With the 50F+ weather I got into my hives today.  All made it through 
the winter, bee numbers are good, all queens are laying nice 
patterns.  No varroa detected on the bees.  Fresh orange and pale 
green pollen coming in.   Evidence of fresh nectar in the cells.  
Crocus started blooming yesterday. :)
