Moved from rufa group.
Thanks Ben, your reasoning sounds good, and it matches up well.

not integra
Not an expert, but I don't think this is integra. I can make out lots of hairs on the head and pronotum of this ant, whereas integra is essentially hairless here. Perhaps this is obscuriventris?

Richard, thanks for correcting my mistake. The habitat was unusual for Formica rufa group, but it sure does look like it belongs with this group.

Oops! Formica Ant (Formica sp.)
Dark legs and clypeus without a notch suggest a member of the rufa-group, maybe F. integra. On the other hand, a nest under a rock, rather than a mound of "thatch", doesn't match well with the rufa-group. Advice of a North-American expert is needed.
