Number 9: the Tarantula hawk wasp, Pepsis hemipepsis: “Blinding, shockingly electric. A running hair drier has been dropped into your bubble bath.”
Very common around here. Attracted to open water, which means they love my outflow pipe. Water a tree, they're there. Easy to spot because of the red wings. Plus they're the size of an F-18.
Fortunately they're about as aggressive as a cottontail. I'm ugly, but not tarantula ugly.
