It has been shown that a light 1:1, or even lighter syrup, is optimal for comb building. However, I have been taught that when bees swarm they feast on honey before departing the hive and use this to quickly build comb upon arrival in their new hive. Honey is a lot thicker than a light syrup or fresh nectar. Could the bees maybe feast on nectar rather than honey, or could they dilute the honey with water before leaving the hive? Is there any research or observation on this? Thank you.
