I was digging in the ground with a trowel looking for centipedes when I unexpectedly dug into this ant hill. Here is a link to a posting of another ant from the same colony:

You don't mention a size difference, but typically, smaller workers of this species are darker in color.

Thanks and...

I measured both this ant and the other one from the same colony. They were each 6 mm jaws to rear. No size difference between the dark one and the lighter one. I'd estimate that about 80% of the ants that I saw were of the darker variety. I collected about a dozen specimens from this colony and have sent them to Dr. Barry Hicks of the Biology Department at the College of the North Atlantic, Carbonear. He has kindly agreed to examine them in his lab and let me know his findings.
