Saw these guys on our potato plants, next to the compost pile (live oak/chaparral habitat), they were tending aphids on the potato plants. I assume the are Linepithema humile.

They sure look like the Argentine ants, right down to the number of antennae segments, that have been IDed as such on other sites I've seen. Here's an index page to a whole bunch of good photos of them, up close and personal, to compare with:

This reminds me...a couple of years back, I remember coming across a photo of 'an Argentine ant queen on the move' which was so totally at the opposite end of the scale to the calibre of your images, say, that I linked to it on an 'Argentine' thread over on an ant forum as a bit of a joke. It had been taken by a professional exterminator and posted on a pest site (where you can sometimes find some really good general info on common ants) in order to illustrate the Argentines' propensity to break up their colonies when hassled by inept attempts to destroy the nests...he'd photographed a colony queen, accompanied by a number of workers, striking out across a kitchen floor in search of a new nesting site. Unfortunately, it looked to have been taken from several feet away and was so incredibly blurry that it could have been nothing but a bunch of white tiles that someone had marked up with a dozen dots and then a dash, using a black crayon. A+ for good intentions, I still grant, but I admit we had some laughs over that one otherwise...
