What type of bee is this?
I have many of these trying to get in my hives. I had a weaker hive that I had started feeding and noticed these got into the hive and up in the top hive feeder so I'm now combining two weaker hives. I'm also putting in an entrance reducer and plugging the cork hole.
In anycase, I'm just trying to understand what type of bee they are and if there is anything I can do. They did quite a bit of damage to the one hive and I'm trying to figure out what I could've done to prevent it.
yellow jacket twice the size of a queen?
that my friend is no yellow jacket. It is what some call a Japanese hornet. I have seen them capture a bee mid flight, they can be kept out of the hive by making the entrance as small as a worker bee no larger.
