Crematogaster, possibly ashmeadi. Maybe Monomorium, I'm not familiar with millimeter measurements and the only easily noticeable difference is size.

Thanks.  The more I look, the more I think these are Monomorium.  The guide I found said Crematogaster has a spine on the rear of the thorax and these don't have them.  (Then again, I've been doing this for three weeks so I really have no clue. )

I agree with the others. The gasters on these queens are too rounded and they are too small to be Crematogaster. I wonder when Monomorium will fly in PA.

This is a Monomorium sp. probably M. minimum
