Specimen Label


This species is a slave-maker of other Temnothorax species. When a nest on Crete was uncovered by Salata, Borowiec & Trichas (2018) 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. Also on Crete, one queenright colony of Temnothorax muellerianus with Temnothorax semiruber as slaves (Buschinger & Douwes, 1990). It is remarkable that Temnothorax semiruber workers are larger than the workers of the slavemaker Temnothorax muellerianus. This contrasts with all other records of this species with other, smaller Temnothorax species.
