I thought I'd do a quick check of my hive this afternoon since it was ~60F. I wanted to see if they had found the sugar I had placed on the newspaper (they haven't). What I did find was some ladybugs that had taken up residence inside the telescoping top and the inner cover. They weren't inside the hive (under the inner cover). Did they just find a warm place to winter over? Should I be concerned? The bees don't seem to be doing anything about them (they're still down in the lower deep).
