For my own peace of mind I would like to have these ants identified so I can be certain of the species that I am observing and reporting on. I live just north of London, Ontario, Canada. I find these ants nesting in the clay loam soil of my garden. They aren't very common in this area. A colony that I keep has grown tremendously in the past two years. I don't know when their nuptial flights are. The background grid in green is 2.5 mm squares.
Thank you for your help with this.
