Workers dying agonizing

[lucascquintal]

I have a young collony of leafcutter ants (around 20 workers), that i assume to be Atta Cephalotes, and today i notice that the major worker was running crazy on the outworlds with her jawls open. After some minutes, or hours because i dont know when she started with this, i notice that she was upside down with no moviment on her four rear legs. She couldnt even turn herself up. When i did it myself she tried to run, but still with no moviment on her four rear legs. I dont know if her intend was to die as far as possible of the nest. Moments ago another worker aproches her and started to run crazy as well and i am concerned she will die too.
Does anyone have any clue about what may have caused this? Please help. I keep the outworld open with no lid, and used vaseline to make it work. Could an spider or other animal like this have attacked the ant??

I attatched 3 short videos i made to illustrate the situation.

I understand that it's been a few days since this incident. If your colony is still ok, I suggest you take the queen and separate her from the workers. They may be very sick. If not, they may be cold and fighting against hibernation.

your ants might have some sort of death circle thing going on they release pheromones to do this circle until they die more and more will come to this deadly cirle
