Abstract Asymmetries in courtship signals can result from
both developmental instability during ontogeny and from
temporary or permanent damage following mating, fight-
ing, or interactions with predators. These two types of
asymmetries, which can be divided into fluctuating asym-
metry (FA) and damage asymmetry (DA), have both been
suggested to play an important role in mate choice as
potential honest indicators of phenotypic and/or genetic
quality, while at the same time, DA may affect ornament
asymmetry in a random manner. Interestingly, despite the
massive research effort that has been devoted to the study
of asymmetry during the past decades, very little is known
about how an individual's behaviour relates to asymmetry.
Here, we measure and characterise asymmetry in morpho-
