The difference between the rufa group and the fusca group is rly simple.They look diffrent their biology is similar not the same (colony structure,etc...) and the biggest noticeable difference is the nest rufa (group) makes nests out of wood pine that are 1m tall or more but fusca stays more on the ground making dirt nests.Also rufa is more in forests and fusca is more like a open field ant. Now for my question does it happen maybe that ants from the rufa group make nests like the fusca or that they inhabit the same environment?


Thank you !

Not all rufa-group Formica build mounds (our Formica integra, for example), and some fusca-group Formica (like our Formica glacialis) build impressive earthen mounds -- less than a meter tall, but sometimes a meter wide, and lightly thatched.

 

Formica from the rufa group are usually two-colored (or at least red), their heads are at least as wide as they are long, and they are lacking a notch in their clypeus (sanguinea-group) or a concave depression at the top of their head (exsecta-group).
