Myrmica rubra, also known as the European fire ant or common red ant, is a species of ant of the genus Myrmica, found all over Europe and in some parts of North America and Asia. They are mainly red in colour, with slightly darker pigmentation on the head. The ants live under stones, fallen trees, and in soil. They are aggressive ants, often attacking rather than running away, and are equipped with a sting, though lack the ability to spray formic acid like the genus Formica.
