It's my first time seeing it ever. Found it in Burbank, California ( 10 minutes away from Downtown Los Angeles )
Whoa nelly!!!! Gorgeous! Gotta be some kind of wolf spider. Suggest searching this marvelous site: http://bugguide.net Thought for a moment it might be a male Phidippus johnsoni, redbacked jumping spider, but they are tiny---unlike yours!
Hmm. Your spider bears resemblance to jumping spiders...Habronattus decorus, for example...but yours is, as previously noted, MUCH larger than H. decorus' 6 mm. length. Whatever its identity, eyes and chelicerae of that size indicate that it makes its living by observing and LEAPING onto its prey. And grasping it tightly. I think that you should submit your photo to BugGuide's ID department. They could not be anything but happy to see your photos, esp. #1---would gladden the heart of any Araneae-lover! Just in time for Halloween...take a look at this face. WARNING: Brace yourself. http://bugguide.net/node/view/255238
