摘要

Dear editor, Mimetic protection is most effective when mimics are relatively rare (Pfennig et al.,2001).In polymorphic damselfly species,male-colored female morphs may avoid costly male mating attempts because they are not immediately recognized as a suitable mating parmer (van Gossum et al.,2008).We investigated morphological resemblance of male-colored females to males across six populations of the polymorphic blue-tailed damselfly Ischnura elegans (Vander Linden).We found that male-colored females resembled males more closely with an increasing ratio of male-colored females to other female morphs.Our results suggest that the degree of mimetic fidelity is frequencydependent.
