4. Length (from head to gaster): around 5 mm (see picture 3)
5. Color, hue, pattern and texture: A rusty red color over the entire body, with hairs all over the body. Shiny gaster.
6. Distinguishing characteristics: two spike-like appendages on the thorax of the ant. This makes me suspect it could be Myrmica rubra. (see picture 2)

Sorry for the blurry pictures, my microscope isn't exactly high-end.
Sorry for the blurry picture. These are the appendages I talked about.
As you can see, it's around 5 mm in length.
