Space Age beardeds, as these are called, have been around a long time. The appendage may be non-existant one year and huge another.

At Blue J Iris, at opening screen, click on Color and Type Categories. Choose Space Agers.

Thank you!!! I had no idea. And you're right - this little appendage was not there last year - that was the first year for them. And I've never heard of BlueJ Iris....thanks again!
