First record and new host record of the obligate dulotic ant, Polyergus bicolor (Hymenoptera: Formicidae), in Alberta, Canada
Keywords:Polyergus bicolor, dulotic parasitism, range expansion, host expansion, Alberta, Formica podzolica
We describe the discovery of Polyergus bicolor, an obligate slave-making ant species, as a new provincial record in Alberta. This species was previously known mostly from eastern Canada and the northeastern United States and has been sparsely collected: only once in the past 50 years. Polyergus bicolor was discovered parasitizing Formica podzolica, which is also a new host for the species. This discovery marks a significant expansion of both range and host for P. bicolor.
