TL;DR: The evolution of mating preferences based on age, and in the relationship between longevity and fitness, are investigated to highlight the importance of understanding sexual selection from a life-history perspective.

TL;DR: The key perceptual principles, namely, retinal photoreception, sensory channels, opponent processing, color constancy, and receptor noise, are discussed, to inform an analytical framework driven by the research question in relation to identifiable viewers and visual tasks of interest.

TL;DR: It is suggested that careful experimentation, using 'natural' manipulations where possible, should prove most beneficial in identifying costs and exploring schedules of contest settlement in this group, and future investigations should be sensitive to the fact that butterfly territoriality and associated male-male interactions are seated within a broader ecological and life-historical context.

TL;DR: The heightened stress sensitivity of the iridescent UV suggests that it offers an informative lifetime indicator of juvenile environments and, henceforth, adult male phenotypic condition, which may be salient to females seeking a highly fertile and/or nutritious male ejaculate.

TL;DR: It is shown conclusively that residency does not serve as an arbitrary cue for contest settlement in this species and it is suggested that more intrinsically aggressive males accumulate as residents and continue to win due to the self-reinforcing effect of prior winning experience.
