Well, I know.
Our kind of bees come out in the high 40's - mid 50's. We have had some really warm Spring-like days, but we haven't seen any bees yet--not even one. So where are they and when are they going to come out? They must know that it's going to become co-o-o-lder again the next day so they say, "it isn't safe to go out." I bet the first one who knows it says that to the other bees in the hive. I am so eager to see them again!
