Hi, welcome to Spider ID. 🙂 This looks like a Johnson Jumper (Salticidae), Phidippus johnsoni.
ok cool. is it poisonous? it is living on in my front steps and I have pets and kids. I don’t want to evict it; if it isn’t a threat it can stay.
Not one to worry about. Not considered to be of medical significance and unlikely to bite except in self defense.
wonderful. then it will live in peace unless a bird picks it off. thank you!
