All adult viviparae (females that give live birth) of this species have wings. This is most likely an oviparae (female that lays eggs), especially considering the location, time of year, and tapering shape of the abdomen / cauda. In temperate climates sexual forms are produced as temperature drops and photoperiod shortens so they can lay eggs that will overwinter. The winged adult in these images is a male, they tend to have shorter, shriveled abdomens.

I am sure you have already seen this Beatriz since they used these images, but for anyone else who is curious, see note referencing this post here:

"I do believe this is Myzocallis asclepiadis… we often find morphs that look like this in September (but not earlier)… our interpretation is that this is the overwintering morph… when we have brought them into the laboratory, they do not reproduce, again suggesting that they are going into diapause.

I also find the pinkish-orange-ish spotted immatures during the summer and don’t have a sense for what that is about… certainly a lot of variation in this species!"

Moved from ID Request.

I didn't read your comment about this being a psyllid, and I made a comment about a somewhat similar aphid which I thought might be a relative. (Wings are close)
