Estimated queen numbers of Formica lemani (with standard errors) from each site within Microdon mutabilis infested (grey) and uninfested (black) colonies. The comparison between Mull infested and uninfested colonies was highly significant; the uninfested populations at St Agnes and Limerick did not differ significantly, and both contained significantly fewer estimated queens per colony than the infested populations (Mull and Burren) (see text).
