I can’t guarantee it was the same species, but when I was growing up in the L.A. area I encountered many jumping spiders similar to this specimen, none of which bit me. On a couple of occasions, though, male spider would start waving their front arms at me as if they were beginning their mating dance. Seemed friendly.
Thanks for providing your valuable anecdotal information on the harmlessness of Jumping Spiders.
I found a Johnson Jumping spider yesterday on the side of my house near some equipment covered with a tarp. Beautiful looking creature.
Thank you! Fascinating info about the Amazing Jumping Spider.
They are very pretty
I have a fantastic picture of a jumping spider that was on my car

This looks like an adult male Paraphidippus aurantius, the emerald jumping spider. Unfortunately, I am not able to enlarge the photo for some reason.
Thanks so much for your comment Barbara. If you click on the image, it should enlarge in a new window.
This is a female Maevia inclemens, the Dimorphic Jumper.
This is another Paraphidippus aurantius (Emerald Jumper.)
Thanks again Barbara.
BugGuide does not list Emerald Jumping Spider as a common name, though the Penn State Entomology Department does recognize that common name.
How do I upload a photo of a spider? It is reddish brown with a white jack o’lantern face on back
