I put a new marked Russian pure Queen in 10 days ago. She was out in 3 days. I waited a week and checked to see if she was laying. I found some 5-6 day old larvae as well as some younger. As I started to put the frames back in my wife said what is that? I looked and there she was with a bright blue spot on her. She is large for a new queen. Here comes the question. Her tail section is not black. It begins as a dark orange for about 3/4 of it then it turns black. All of my other Russian Queens were black.
