Ectoparasite Community Structure of Two Bats (Myotis lucifugus and M. septentrionalis) from the Maritimes of Canada

Table 3

Mean intensity (standard deviation and range) of ectoparasites among the different host groups at all sample sites in Nova Scotia and New Brunswick during swarming, Aug–Oct 2010.

*There was no difference in prevalence among genders for young of the year, so they were combined for analysis.
