Formicidae. Genus Tetramorium? - Tetramorium immigrans
Saginaw, SVSU Campus, 43°30.4’N 85°57.4’W , Saginaw County, Michigan, USA February 1, 2010 Size: ~3 mm
Tried to key it out and came up with Tetramorium for the genus. Any opinion on that?
Found munching away on corn chip inside the SVSU campus with a couple others.
