Ant Tending Karner Larvae - Formica

Ant Tending Karner Larvae - Formica

Can the ant experts I.D. this ant (thinking it might be a Campanotus sp?) that is tending this Karner Blue larvae? I've seen C. novaboracensis tending them, but was wondering which one this is with the red head and thorax. Thank you!! Kenny.

It is treacherous to ID microgyna group species without specimens in hand. This does look like it could be F. difficilis, the most abundant eastern species.

While we're at it and for the record, F. nitidiventris & F. schaufussi are now correctly known as F. pallidefulva & F. dolosa.

This is a Formica species. I'
This is a Formica species. I'm not certain which at this time.

Thank you MrILove!, and for your interest
found a paper on Karners circa 90's and they give these Formica species for New York ants that attend larvae, might one seem more "near" for you as a best guess? Again, THANK YOU! Kenny.
