Significantly more alighting responses by males on or near females that could move their wings than on females that could not (mean ± SE: 34.10 ± 3.76 vs.

20.60 ± 3.79; n = 10, flies mounted on their abdominal ventrum to leave their legs without support and thus induce a wing fanning response.

For each recording event, we placed 50 young or 50 old male or female flies into a wire mesh cage fitted with a cool-white LED.

Following each recording, which typically captured 1–6 flies in free flight, we proceeded to the next recording with a new set of flies in another cage.

Analyzing the video-recorded data files (e.g.; Additional file 3: Video S1; Additional file 4: Video S2), we found differences in the frequency of light flashes reflected off the wings of free-flying young and old females and young and old males (one-way ANOVA; : Data S1).

, under direct light at 15,000 frames per second revealed that wing movements produce a single, reflected light flash per wing beat.

Such light flashes were not evident when we video-recorded wing movements under diffuse light.
