Ant pile in Idaho (Tricia, Boise, Idaho, USA)

At a trip today (July 10th) to Boise's MK Nature Center (operated by Fish and Game) our group of preschoolers found a pile of ants. I told them I wasn't sure what they were doing, but I would take a picture and ask someone. So, I found you online! These are just small black pavement ants, I believe. Any insight on what they are up to?

Thank you for your time,


Dear Tricia,

Thank you for sending in the photo of the ants your preschoolers noticed on your recent nature trip. Great find!

The ants are in fact pavement ants in the genus Tetramorium. Although this is a common ant found in urban environments, it can also be found in more natural habitats. Along with the pavement ant, there are likely dozens of other ant species in that same nature reserve, so keep your eyes open the next time you visit the reserve. Close by in the state of Utah over 150 species of ants are known (see the Ants of Utah on

You can read more about pavement ants here in a previous AntBlog post.

Thank you,
