Re: Dead Bees under harvested supers
If you put honey out in the open there is more than honey bees that come to the feast. I do this on occasion. depending on how much honey there is there will be a lot of honeybees then the wasps, fly's, bugs of all sorts and then big fat mean bees that bully they way in and take over what is left.
I don't see this as a huge mistake because the season is winding down and the old bees are near their end anyway. I suspect that is why they fight so hard. In about three or four days they will forget it ever happened because they can't remember much longer than that. I haven't witnessed a robbing of the hive due to open feeding. They remember where the honey was for about two days it seems and then they give up as long as you don't add another plate to the feast. I have just about another cup of cappings that is mostly honey from harvests in the past left to give to my bees and then I will get a new supply this year.
