What do you think this is? It was large, say 1.5 inches long, and fast-crawling. Thanks!

Hi Jodi,
This is a Potato Bug or Jerusalem Cricket, a common Southern California insect.  It is interesting that they live on Alcatraz and we wonder how long it has been since the Alcatraz population has mixed and interbred with the mainland species.
