Biology

An inquiline ant living within the nests of their host species Leptothorax acervorum, in sticks, pieces of bark and tree stumps in coniferous forests. The species is workerless and apparently host-queen tolerant.

The alate gynes practice female calling outside their natal nest. Mating takes place on the ground, often on top of the nest.

The three species L. pacis, Leptothorax kutteri and Leptothorax goesswaldi all are workerless, permanent parasites of Leptothorax acervorum.
