Small males are more symmetrical: mating success in the midge Chironomus plumosus L. (Diptera: Chironomidae)

Research conducted in Chironomus plumosus midges find that the mating success depends on the fluctuating asymmetry in the male characters, and the success of symmetrical male is due to his improved aerobatic ability. Male Chironomus plumosus, successful at acquiring mates, show lower levels of fluctuating asymmetry in the length of wing than their rivals. Small males are found to be more successful in acquiring mates.
