Who was that dashing ant of mystery and intrigue?
Tetramorium simillimum is a small myrmicine that has tramped around the globe with human commerce, quietly inserting itself into native ecosystems. Like most insect species, little is known about its behavior or its interactions with other species.

An excellent question, Jason. If you look at Chart2 on this page you'll see some differences in head shape and petiole shape.
