I've been playing the ultimate edition of Fallout New Vegas, trying to complete as many of the side quests as possible, I find the Cazador wasps to be annoying and a little bit scary at the same time, of course in the game they're giant mutant wasps.
Finding this on my morning walk last week was pretty startling, I haven't seen one of these in years. The one I saw was about as long as my thumb, just not quite as wide.
Right after posting this I went back to playing the game, walked out of a cave in Zion and was attacked by 2 of these wasps, the ones in the game, the real ones are actually not aggressive unless disturbed.
