Myrmica ruginodis

Myrmica ruginodis can be distinguished from Myrmica rubra by the length of pair of spines projecting from the rear of the main part of the thorax. In Myrmica rugodinis these spines are relatively long - as long as the distance between their tips.

Myrmica rubra is the other common red ant but this has short spines protruding from the petiole.
