Formica fusca group, almost certainly subsericea, however there are some rarer species that cannot be definitively ruled out. We would need to see the relative density of the pubescence on the third and fourth tergites and/or the presence or absence of large punctures on the malar area in order to distinguish it from F. argentea, and the relative density of the gaster pubescence and pilosity to separate from species like subaenescens, podzolica, or glacialis.

Pretty sure this is fusca group, but I would rather have people more experienced than me come to a conclusion.
I know its probably quite hard to nail a species down, but I'm guessing this is subsericea.
Approximately 10mm.

Wow she looks aggressive in that first photo! And pretty fat with food! Formica subsericea is my guess.
Currently raising:
Myrmica rubra (1 queen + ~5 workers)
Lasius niger (single queen + ~90+ workers)
Lasius neoniger (3 single queen + brood)
Formica spp. (Queen [likely parasitic, needs brood])
Formica pacifica (Queen)
Also keeping a friend's tetramorium immigrans for the foreseeable future. Thanks CoffeBlock!

If it’s any help in direct sunlight the gaster is highly silver in color.It could also be F. neogagates but I don't see any silver band on the gaster from these pics indicating F. subsericea. Although it still could be F. subsericea.

Then yeah that's definitely F. subsericea (as from what I know, F. neogagates is a completely solid color with no silver effect to the gaster. The setae on their gaster comparatively is the same exact as F. subsericea at least to the naked eye).If it’s any help in direct sunlight the gaster is highly silver in color.It could also be F. neogagates but I don't see any silver band on the gaster from these pics indicating F. subsericea. Although it still could be F. subsericea.

I did find the queen in a field woodland border, with a marsh nearby. I don’t know if that’s any indication of species however.Then yeah that's definitely F. subsericea (as from what I know, F. neogagates is a completely solid color with no silver effect to the gaster. The setae on their gaster comparatively is the same exact as F. subsericea at leastIf it’s any help in direct sunlight the gaster is highly silver in color.

Currently keeping:
1x Formica subsericea, (used to be polygynous) 15+ workers with 4 pupa (Idk why they still have)
1x Lasius umbratus, (Workers accepted) 5+ workers with host brood
1x Ponera pennsylvanica, just queen
As you watch your ants march, remember: every journey begins with a single step (or queen)-not just towards you, but towards a future woven by diligence and shared dreams - Me

Formica fusca group, almost certainly subsericea, however there are some rarer species that cannot be definitively ruled out. We would need to see the relative density of the pubescence on the third and fourth tergites and/or the presence or absence of large punctures on the malar area in order to distinguish it from F. argentea, and the relative density of the gaster pubescence and pilosity to separate from species like subaenescens, podzolica, or glacialis.

Even though it doesn't matter, I probably will take pictures of those regions you listed and post it here. If you do reread this thread and find the pictures then it would be cool to know exact species if the pictures are adequate.
