To begin, cue a little musical accompaniment.
Much like the people who have historically populated the city of San Francisco, the insect population there varies from run-of-the-mill-regular-guys to totally-out-there-creatures. It is not particularly fun to discuss the average man, nor the average bug. Instead, I have hand picked some of the more exotic characters. It's time to turn on, tune in, and bug out.
Let's begin with the velvet ant, known by people who actually read their textbooks as "Dasymutilla aureola". The velvet ant looks like an ant who is wearing a shag carpet. He is not technically an ant (he is actually a wasp), and is not much of a target for San Francisco exterminators, since he is pretty rare for most of the year, and is more fashionable than dangerous. He would fit in exceptionally well at, say, Burning Man. In fact, I found a photo of a man at Burning Man who wore a similar getup to his wedding, which was at Burning Man.
