Bugs, of course, will be a prominent feature of any story within his subgenre. This said, they may well be organic, mechanic, electronic, or a mix of them all.

With input from cyberpunk and biopunk, perhaps with a sprinkle of fantasy or alien invasion, this subgenre has the potential to be horrific and awesome on a new level. 

Perhaps the bugs come from outer space? Are augmented by technology? Or they are simply humanity's successors in a dystopian world. 

And of course, there may also be bugs in a system... or remote-controlled survey bugs. And what about a  world where the only available source of proteins are bugs?

A few examples of bugpunk include The Tower and Hive-Series by Anne McCaffrey, The Starship Troopers movie, Ender's Game by Orson Scott Card, or the Manga The Terra Formars.
