Genus Dolichoderus

So I managed to find a group of ants that were on a banana leaf, at first I didn't know the reason why the ants formed a very large group, but after I noticed it turned out that the ants were picking up bird droppings that were stuck on the banana leaf, but I didn't know what kind of bird droppings it was. After knowing this, the size of the ants was very small so it was very difficult for me to take pictures of them, so I immediately zoomed my cellphone camera as large as possible so that when I took pictures of the ants they could be seen clearly, and I succeeded in doing so, and now I will share pictures of all the ants here.
