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.

    $\begingroup$ moths don't have 2 wings they have 4 wings, the forewings and hindwings are just being held apart in this image. en.wikipedia.org/wiki/External_morphology_of_Lepidoptera $\endgroup$ – John Jul 29 '18 at 3:05
  • $\begingroup$ @John oh, that makes quite a bit of sense. Do you think this is in fact a moth? I've just guessed at that. $\endgroup$ – uhoh Jul 29 '18 at 3:31

    $\begingroup$ Yes definitely a moth, although I have no idea what the species is. You could ask for identification as a separate question. just be sure to include the last sentence of the post, where it is found is very helpful. $\endgroup$ – John Jul 29 '18 at 3:35
  • $\begingroup$ Okay thanks. I'm still interested in how these wings would OPEN (be deployed) without bumping into each other. There must be some kind of rotation involved; perhaps the ones that are vertical in the photo would rotate forward first? $\endgroup$ – uhoh Jul 29 '18 at 6:53

    $\begingroup$ Not a moth. It is a skipper. Family Hesperiidae. davesgarden.com/guides/articles/view/5254 $\endgroup$ – Karl Kjer Jul 29 '18 at 12:17
