When I first read your comment, I read "Xian" as the common shorthand for "Christian" and wondered for a moment if yet another apocalyptic sect is doing their best to make my whole religion look crazy. And then I realized that if a new religious cult does appear whose worship centers around the cicada invasion, I will not be in the least tiny little bit surprised.

I did consider personal ads in newspapers instead (I know people who've met and had long-term relationships that way), but I'm having trouble imagining a cicada who could lift a heavy newspaper or even turn the pages. Maybe a bunch of bugs working together could do it...
