Pitfall trapping revealed that the European fire ant, Myrmica rubra (Linnaeus) (Hymenoptera: Formicidae), represents an unusual example of a temperate invasive ant species. In British Columbia, Canada, M. rubrapopulations are associated with a decreased incidence and abundance of other ant species in three different plant communities when compared with M. rubra-free control areas. M. rubra represented more than 99.99% of the total ant fauna caught in the infested areas, and the numbers of M. rubra captured in the plant communities ranged from over 10 times to over 1300 times the total number of all ants collected in corresponding M. rubra-free areas. Total numbers of some taxa of insects and non-insect arthropods, including those likely to be competitors or prey of M. rubra, were reduced where the invasive species was present. Biodiversity indexes for the overall suite of captured arthropod species were lower where M. rubra was present in all three plant communities but most of this decrease can be attributed to the difference in the ant fauna.
