Thank you, Jeff, for verifying what I suspected from my own video as well as for providing a link to that close in, crystal clear look at a Skipper and its proboscis. My film isn't that close and clear, but when I view it in slow motion, the Painted Lady cleans her proboscis first with one leg and then with the other. In real time, she did it for almost twenty seconds. I'd have posted that film, but your site seemed to require a photo. I will be posting a short movie about the Painted Lady in a day or so. It will include that slo-mo footage now that I can state with confidence that she is indeed cleaning her proboscis. I assume that sticky pollen has to be cleaned off from time to time.
