Formica paralugubris is a species of ant. It is a member of the Formica rufa species group native to the Alps in the Palearctic realm. It is a cryptic species, often miscategorized as Formica lugubris due to morphological similarities. The two species are capable of differentiating one another, however; F. paralugubris ants react aggressively towards F. lugubris ants.Formica paralugubris differs in its organization as a supercolony. It has been introduced into North America with the import of pine trees. It does not exhibit characteristics found in other invasive species due to its limited native range.
