Took this shot at the base of the Weeping Wall, Suicide Rock, CA.
It was about 1/2 inch long and moved very fast.
Is this a commonly known type of spider?

Yup...Red Back Jumping Spider.
Not sure what it is about jumping spiders, but I like them. They don't creep me out like other spiders.

A friend did his dissertation on the optical nerve system of them guys!
Imagine operating on one of them. Now he designs electric car motors and
controllers. Hey, it's all electrical he says.

The spiders that really got my attention were the bird eating spiders in the Orinoco River Basin in Venezuela.

Found this bad mama walking down the street near my house a few weeks back. Kept her in a jar and fed her grasshoppers for a couple of weeks to fatten up before winter. Needless to say, she got relocated a little further from the house when I let her back into the wild.
I get the impression that hairy spiders give a lot of folks the heebie-jeebies. Nope, for me it's these. Like they've been gorgeously designed to send my monkey brain running. But I'm a highly-evolved, rational monkey (sort of). When I found her I scooped her up in my hat and had to rotate the thing constantly for about 15 minutes to keep her from getting to close to my fingers. She had my undivided attention the whole walk home.

PS - That's not a Red-backed Jumping Spider, aka the Johnson Jumper (Phippidus johnsoni).
It's the closely related Phidippus adumbratus. Note those banded legs. Also, Red-backeds have red restricted to the abdomen.

Are you sure it was a Black Widow? That's an awfully dramatic/atypical reaction...

A spider I met a couple weeks ago. Although its optics are small it had no trouble keeping track of where I moved.

Takes me way back to Kenneth Roeder's Nerve Cells and Insect Behavior
Second, single neurons exhibit some surprisingly rich examples of
computational sophistication in terms of (a) temporal dynamics (coding superimposed upon circadian and shorter-term rhythms),
and also (b) what Kenneth Roeder called ‘neural parsimony’: that optimal information can be encoded, and complex acts of
sensorimotor coordination can be mediated, by small ensembles of cells
Analysis of neuronal oscillators for rhythmic behavior have
delineated a profound influence of sensory feedback on interneuronal circuits: they are not only modulated by feedback, but may
be substantially reconfigured. Additionally, insect motor circuits provide potent examples of neuronal restructuring during an
organism’s lifetime, as well as insights on how circuits have been modified across evolutionary time.

Nobody has mentioned Spider kletter shoes yet? Who made those?
And MH2, that's one of the best photos I've seen on this rag.

Hey I'm walkin here!
but then
She was common, flirty, she looked about thirty
I would have run away but I was on my own
She told me later, she's a machine operator
She said she liked the way I held the microphone
I said "My, my" like the spider to a fly
"Jump right ahead in my web"
So much for higher education. Hope I don't have to pay back that NDEA Fellowship.

That's not a Brown Recluse.
BR's live in webs, they don't roam around the yard.

Strange, I hate almost all spiders. They freak me out. But I jumping spiders are the coolest things around. Every year there are a few in our kitchen around our funky bay window looking thing. We let them hang as long as they wish.

We try not to squash spiders up here in squish, just another reason for it to rain. Besides they like to eat much more annoying bugs. Judging by the weather lately someone has been squishing a lot of spiders around here I suspect.

That's a beautiful spider!
And that one in the grass looks like a Brown Recluse. They like to f*ck around in the grass and sh*t. Was it smaller than a quarter?
If it was bigger, then it's your average house spider, who can get quite big if you feed them other bugs. :)

Tweakers like the f*ck around in weird places. Who knows man. I walked into my apartment about a month ago and there was a black widow hangin from my ceiling just chillin about waste level.
Spiders are weird little things.

Best, it is a sowbug spider. They look scary as hell if you see them with their fangs open but they generally hide and don't bite people. They are reasonably venomous though.

Was hitch-hiking up to Merced to try and locate mouse when I ran into this guy - out of either curiosity or kindness, I suppose, can anyone identify it?
