Movie 2.
Jalmenus evagoras male exhibiting a typical inspection response towards a robotic flapper. During the polarization discrimination behavioral experiments, only responses that showed all the features exemplified in the video above were recorded: a clear deviation from the previous flight path, a pause to inspect (sometimes brief) and then resumption of normal flight. Video is taken on an Apple Iphone 6 using the ‘slow-motion’ video capture and edited in Adobe Premiere Pro 2020 to increase sharpness and clarity using the “unsharp mask” function.
