Because there are a lot of them about, I’m guessing that this is a wing from a Riley’s 13-year cicada (Magicicada tredecim) like the one whose picture I posted ten days ago (see: Saturday, May 20, 2017). I think it’s a beautiful thing. It’s also quite sturdy. This one was separated from its owner and has little droplets of water on it. Even handling it to get it into position for a photo didn’t dislodge them. Interestingly, the wings of the clanger cicada (Psaltoda claripennis, also known as the clear wing cicada), a species found in eastern Australia, has a physical structure of ‘nanopillars’ that kill bacteria that settle on them. Pretty cool.
