Galerina sp. perhaps.7.17.10 dwb / gadsden co. florida
The ants first two segments are red and their rear or third segment is completely black I would say they are about 3-4 millimeters long. Update: I did some research and found out that Pharaoh ants are common Florida ants that vary from yellow to red. There is a bunch of small colonies around the park for now I have seen 4 colonies. They are considered pests but they are very cute to be frank.
The middle is yellow if you pop them and they are soft enough to just pop with your finger
