I'm having trouble understanding how these wings might work. Are they somehow folded or bent by 90 degrees so that part of the wing is vertical and part is horizontal to be more compact?
If so, how mechanically are they then made quickly more rigid and straight each time it enters flight, which should be fast to avoid being eaten?
Also, I'm guessing this is some kind of moth, but I have no idea. I don't really need an exact species ID, but some classification guidance would be appreciated!
This individual is about 2 cm long, and was seen recently (late July) in Taipei, on a hot, sunny day.
