Fluctuating asymmetry, size and mating success in males of Ischnura elegans (Vander Linden) (Odonata: Coenagrionidae)
Article Abstract:
Studies on fluctuating asymmetry (FA) should include a multivariate investigation of the role of other factors influencing fitness, particularly body size. Research in this area has considered the connections between mating success of males, body size and FA for both wing length and number of setae on the legs of the damselfly, Ischnura elegans. It was found that male mating success is negatively connected with body size, calculated from wing length, but not with the number of spiniform setae on the legs. Univariate analyses showed that males with a lower level of fluctuating asymmetry seemed to have a higher mating success.

Fluctuating asymmetry, mating success, body size and heterozygosity in Coenagrion scitulum
Article Abstract:
Research describing the effects of fluctuating asymmetry with respect to several fitness components in a Mediterranean damselfly are presented. An analysis of the results suggests that some of the variables are interdependent.

Male choice of female colour morphs in Ischnura elegans (Odonata, Coenagrionidae): testing the hypotheses
Article Abstract:
Research focusing on five populations of the damselfly species Ischnura elegans has sought to distinguish between the hypothesis that males prefer to mate with gynochrome females and the hypothesis that males are attracted to the most common morph in the population. It was established that males are able to distinguish between androchrome and gynochrome female morphs. However, they do not discriminate between the two adult gynochrome female morphs. In this species, males mate mainly with the most common female colour morph in the population.
