As I said in the title, there appears to be an ant on the queens back leg. Today I introduced some new worker from the same colony as the last. Then later when I checked on them again this snt was on it. It appears to be dead to. It's not moving. I';m not sure what I should do about it. It appears that it's stuck on the queen. If you have any tips to remove them they would be appreciated. My guess is ant ant grabbed onto her and some how died.
Here are some images and a video:
