Just thought I'd show the nest entrances to some of the wild ant colonies that are at my house.
Trachymyrmex septentrionalis
Pogonomyrmex badius
The sand piles of these will be a lot larger in the summer.
Odontomachus brunneus
(Both nests are at the bases of trees)
Dorymyrmex bureni
Pheidole obscurithorax
The sand piles of this species usually look more like Trachymyrmex or Dorymyrmex and are larger, but I couldn't find any good ones today.
Pheidole dentata
The nest entrance is to the right, underneath the leaves.
Pheidole bicarinata
These nests are absolutely tiny, but they are everywhere.
Psuedomyrmex gracilis
Solenopsis invicta
This is one colony. The nest is several feet long, and is not the usual mound that these colonies make.
