Myrmica rubra
European fire ant, common red ant
Myrmica rubra is a widespread Palaearctic ant species native to Europe, now invasive in parts of North America and Asia. Workers are reddish-brown with darker heads, 3.5–5.5 mm in length. The species exhibits complex social structure with both macrogynes and microgynes, and colonies are polygyne and polydomous. It serves as a host for several myrmecophilous butterflies and has been documented transmitting viruses through scavenging behavior.
