One trait that is commonly lost is the worker caste, the functions of which are adequately fulfilled by host workers. The few inqu...

Nevertheless, such species have received little phylogeographic attention. Here, we investigated the Pleistocene refugia and subsequent postglacial colonization of the common, abundan...
