Dry Sugar Feed for Winter

For the winter I place dry sugar on the inner cover as emergency food for my bees.  Many folks put it on the top bar, using newspaper to hold it.  I've found putting it on the inner cover is easier and just as effective.  The second photo is a cluster that was checking me out as I removed a box and lowered the inner cover.  I was very late getting this hive ready for winter due to a longer vacation.
