Ctenucha rubroscapus it is!
The fascinating moth, subject of my post a few days ago, has attracted some attention. A follower in Davis and a few others have determined it's the Red-Shouldered Ctenucha, Ctenucha rubroscapus. Several web sites report that very little is known about it. They say Ctenuchas lay eggs and pupate on grass, sedges, and irises, but no one reports its adult habits. I've reported to a couple of websites that invite such that all the ones I've seen are frolicking on Pennyroyal. At least it looks like frolicking. I should add that when they swarmed on a recent day, they seemed to have lost some of that skittishness that wouldn't allow me to approach closely. A six-year-old hiker with me caught one by hand. Then I caught one. We watched them for a while in our bug jars then released them. I discourage kids from "collecting" bugs [i. e., killing and pinning] as they can learn so much more by patiently observing them alive. Thanks to all the followers who wrote me about this moth.
