It can be found in the following regions: Russia, Italy, Norway, Germany, Denmark, Albania, Turkey, Romania, and Bulgaria.

These habitats suit it since it builds its nests in rotting logs and stumps, underneath bark, and under rocks.

[citation needed] Harpagoxenus sublaevis is a yellow to brown ant that has different morphs within the species depending on their role in the colony.

Workers will also vary in size depending on nutrient availability and even what their host species is.

When ready to mate, females will exit the nest and climb nearby vegetation such as some grass or a twig and stay there with their gaster erect.

[citation needed] Harpagoxenus sublaevis colonies are believed to have a lifetime of about ten years.

[9] Slave raids occur largely during the same time of year as the sexual calling from female H. sublaevis happens.

[3] These raids are very violent and destructive and cause the host species' colony to suffer a significant reduction in life expectancy.
