Temnothorax corsicus is a socially parasitic ant species known from Southern Europe, more specifically from Italy, France and Croatia.

[1][2] It is most closely related to Temnothorax adlerzi, a species from Greece with a very similar life cycle.

[3] Sibling T. corsicus queens and males mate within their natal nest throughout Autumn and remain there until early Spring, when they disperse and infiltrate colonies of Temnothorax exilis.

The parasite is therefore able to lay its own eggs, which are taken care of by the host workers and develop into new T. corsicus males and queens by Autumn the same year.

Therefore the parasitized colony has a very short life expectancy (~3 years) and is extinguished once the last host workers have died out.
