Hiking in low mountains in northern Taiwan in early May I noticed that something seemed to be looking at me from the ground, and it turned out to be the pattern on an insect's wings.
The wings are fuzzy like a moth or butterfly but they fold back.
There is also a striking face-like pattern on the wings, one "eye" with heavy upper eyelid on each and a "mouth" across both, and it has very long black (or blue?) and white densely-striped antennae or feelers which project straight forward, and it's legs were also black with several white bands. The length from head to wingtips (not counting antennae) was about 2 or 2.5 cm.
I also got the distinct impression that its orientation was not flat (parallel to the leaf's surface) but oriented with its rear high, so that something in front of it could see the "face". I don't have a photo from the side but based on judging things from what is and isn't in focus I think it's pretty clear.
Question: Is it possible to identify this insect with a big “face” pattern on its brown fuzzy wings? Is it also possible to know if the pattern has some underlying structural function within the wings, or is it only for appearance?
