Went down about 2:30 this afternoon expecting to see no activity, but instead on one hive there were probably 50 or so flying about and on the porch crowding in and out of the 3/4 X 3/8 entrance. Sunny, clear, no wind and only 39 degrees F (about 4 C) for the high. This was the nicest day this week - I figure they needed to take a leak.
