Yeah, I hate throwing swarms! Drawn comb is a beekeepers best friend and I still need alot more!Truth be told I know that most of the swarms I trap are from my own hives. Also, I actually think that my swarm management is improving. Two years ago I caught 18. Last year 10. So far this year 4. All the same, when I saw that green mark…..I said bad things.
Another reason, in my opinion. I have a four year old queen in one of my hives. I wouldn't know that without her being marked.That's the only reason I'd consider marking a queen. Sometimes it's difficult to tell which hive they've come from, or if they're feral bee's. Marking kind of solves that issue.
I'm not sure what notes you are referring to. I have had several queens last into their fourth year.....marks intact. I've never had one go to five.I've never had a 4 yr. old queen that still had paint on her thorax. I'd refer to notes in that case.
