I found a trail of S. Xyloni in my back yard. I can't tell where the actual nest is, it might be between a crack in the cement or in my neighbors back yard.
I put down some saturated sugar water that i have fed to my ants just to see their reaction. As you can tell by the photos they went "wild" for it.
there's also a couple photos of ant holes in my driveway. These were dug my an unidentified species of black ants.
