Cicada in Placerville

Friday night, whilst minding my own business in Placerville, one of these things dropped on my head. I quickly knocked it off but had that uncertain feeling so I brushed my t-shirt and at first mentally rejected the large new crusty broach I discovered. On second take, I quickly brushed off the broach too. It makes me shudder to think about it but this thing was at least 3 inches long. Unbelievable!
