Timandra stueningi (史氏褐线尺蛾).
It has been a bumper week for moths. Like many others, this one was hiding in the new growth on Yuelu Mountain. They are named after Timandra the mythological daughter of Tyndareus and Leda, and sister of Helen of Troy and Clytemnestra. Like her more famous sisters, Timandra was an unfaithful wife, but now she has a genus of moths named after her, so things worked out.
