Common Spider - Need ID

[Voracious]

Here's my new spidey, eating the dinner I caught and provided. I saw these guys as little spiderlings under the deck a couple weeks back, and now we're encountering them frequently - which is fine because flies get thick around here. I thought I'd catch one and keep it. It's probably something common.

Can anyone out there venture an ID? This is in western Wash. State.

This little guy ate that fly yesterday - he sucked on it probably most of the night! - and is now about 30-40% larger! The abdomen has darkened, too. The fly offered today was refused. How often do these fellows eat?

I added some plastic flowers to the jar, but this spider has not begun to spin a web. I wonder if it's a Hobo...

hrmm. It sort of looks like a Thomisid crab spider. The length of the first pair of legs kinda makes me lean that way. Can you get any more pics of the bugger?

If I had to venture a guess, I'd say a crab spider of some sort (Thomisidae or Philodromidae). In "Spiders and their Kin" by Levi and Levi the illustrations of the genus Xysticus and Coriarachne appear to be possibilities.

Edit: Ach! WithCerebus beat me to it!

Crab spider but better pics will get you an ID.

Thanks everyone, for the input. I should be able to bring up more info on this fellow now

Wade: Thanks for the book reference: Levi, "Spiders and their Kin". Will have to check it out.
