The idea I had was for a single initial bug, that ‘assimilates’ other bugs it comes in contact with, with the limitation that once assimilated the bugs need to stay in range of the swarm or fall comatose. I’m somewhat partial to the idea of something as universally unnerving as a swarm of bugs figuring out magic because it wants friends. 

That said, if I am limited to a single bug, as much as I love cockroaches, I think I’d have to go with a spider instead. That fits the best in my mind.

We will still love you, even if you’re a worm.
Or in this circumstance, a spider.
