This is a black spiny ant and this ant has a relatively larger size than the other ants, I don't know what this ant is doing, at first I thought this ant was dead, but when I tried to touch it, this ant suddenly moved and tried to escape, I continued to pay attention to the behavior of this ant and it looked very strange.
This ant looked very weak, and often lowered his head down which looked like he was heartbroken, I felt quite sorry for him but I couldn't do anything. At that time I tried to take a picture of him and because this ant was weak so I could take a picture of him easily.
I think this ant is also separated from its colony, there are no other ants visible on this tree, what a poor ant
