I had no idea. It looks like it primarily is going for fluid. And not probing deeply into the spittle to get closer to the nymph. I wonder if the froth is sugary? I bet not, otherwise ants would be interested. Thanks for sharing.

Abstract: Nymphs of the cercopid Aphrophora cribrata cover themselves with a frothy exudate while ingesting sap from their preferred host plant, the eastern white pine, Pinus strobus. Chemical analyses of froth collected from A. cribrata nymphs revealed an array of metabolites belonging to five chemical classes, including fatty acid-derived alcohols, c-lactones and a single 1-monoacylglycerol, as well as the polyol pinitol and the polyhydroxyalkanoate, poly-3-hydroxybutyrate. Bioassays showed the natural A. cribata froth, as well as a synthetic mixture comprised of representative compound classes identified therein, to be repellent to ants but largely devoid of topical irritancy in tests with cockroaches.

I was surprised to see the males lekking above pussy willow as I had not read about that behavior. I'm wondering if anyone else has seen this. Also, does anyone actually have a female in their collection? I do not think I have seen one yet and all the specimens at UCONN were males. Here is a video showing the lekking behavior (the last section is slowed down by 2x). UInfortunately, it only shows one male flying at a time. I have seen groups of over 20 and maybe 30, but typically 1 to 5.. There are some still photos of up to four males in the frame at the end. https://vimeo.com/432643676 I would enjoy comparing notes with anyone else who has been observing A. purpurea.

But I see this species occasionally, usually on Fleabane (Erigeron), and was wondering while trying to take a photograph of one two days ago if the color was strutural rather than pigment; as the wings look mostly black from most angles, but quite purple from some angles. Here is a photo I took two days ago of one; it took many tries to show this much purple. http://www.nyx.net/~dhcox/adela2.jpg I've read about structural colors in butterflies, but not moths, so I was curious.
