02Description

Species Profile

The erratic ant is a species of dolichoderine ant first described in 1789 by Latreille.

The Erratic Ant faces severe population declines due to habitat destruction from urbanization and agricultural expansion across its European range. Climate change is altering the temperature and moisture conditions of its specialized microhabitats, while invasive ant species compete for resources and nesting sites.
