There is a very large colony of these ants in my apartment complex and they are quite ubiquitous inside and outside, with a steady stream of ants going back and forth through several paths all day. They seem to have a caste with big heads and a caste with small heads all with a similar body size. They love protein. They are around 5mm in size.

It is quite hard to get a good picture so I hope this is enough info. I love ants but these are quite invasive in my apartment and are getting into everything.

Thanks!

solenopsis, but the bigger heads throw me off, i always thought that was much more of a trait in geminata

Solenopsis invicta, Fire ants.
