Temnothorax muellerianus

This species is a social parasite of other Temnothorax species, and on Crete it has been collected from the nests of Temnothorax exilis. When uncovered both gyne and workers were hiding in soil while host species workers were trying to hide pupae and eggs. Infected nests were located in very dry and sunny localities (Salata, Borowiec & Trichas, 2018).
