"Love at first flight: wing interference patterns are species-specific " by Nathan J. Butterworth, Thomas E. White et al.
Wing interference patterns (WIPs) are stable structural colours displayed on insect wings which are only visible at specific viewing geometries and against certain backgrounds. These patterns are widespread among flies and wasps, and growing evidence suggests that they may function as species- and sex-specific mating cues in a range of taxa. As such, it is expected that WIPs should differ between species and show clear sexual dimorphisms. However, the true extent to which WIPs vary between species, sexes and individuals is currently unclear, as previous studies have only taken a qualitative ap...
