This I'm certain is a Formica worker. I was hoping to narrow it down to at least a few possible species groups. I realize this might not be possible.

 

1. She was on a myrmecophilious plant in a local nature park. 

 

2. Found 21 June, 2019


3. In a prairie type setting, somewhat dense foiliage nearby. No trees in the immediate area.


4. 6mm


5. Solid black


6. Abdomen somewhat pilose

Looks like something in the Formica fusca group. Consider F. argentea.

Ya, Formica argentea, due to the duller/blunter body, the slight reddish/black bi-coloration, and the amount of pubescence on the rear gaster segments

How did you determine it was Fusca group? The mandibles weren't really in focus.

I use the shape of the head and body structure.

Fusca group Formica are determined by offset teeth at the mandibles, or at least that's what Antwiki says.

 

I was fairly sure myself it was fusca-group, but wanted to get more opinions.

Well when ever I find Fusca group ants, I know right away because of the build of the body. I guess I've just been around Fusca group Formica for too long :lol:. The only Serviformica I've ever kept have been either Formica fusca group, or Formica pallidefullva group, so I've gotten to know how to identify them.
