The photo above showing a cold looking beehive in Bethesda, Maryland was taken on January 31, 2009. With temperatures of 25° F (-4° C), as they were on this midwinter’s day, there's not exactly a beehive of activity around beehives. Honeybees don't hibernate like many insects, but instead feed on their meal-ready-to-eat (MRE) -- honey. If they've eaten it all, beekeepers feed them sugar water, as shown on the far right hive (usually there is a box over the jar, as on the two hives on the left). The bees cluster close together whenever temperatures are below 55° F (13° C). Several of the bees in the middle of the crowd will turn on their flight muscles creating in affect a miniature furnace that helps them make it through the winter, even in such cold places as Minnesota. They keep their nursery (the queen and larvae in the center of the cluster) at a tropical 93° F (33° C), as long as they don't run out of honey or sugar. But spring is around the corner.
