Deane, 
Looks to beone of the Lycosidae family, a wolf spider.
Thank you.
Another source identified this as Thanatus formicinus, a false crab spider. It looks like a perfect match.
I agree. It isn’t one that we know from memory. We mostly work from what we’ve memorized. https://www.bugguide.net/node/view/245938 It’s an interesting spider. Bugguide.net doesn’t have any photos submitted from Idaho of the species. It’s okay to submit a phlto to multiple sites. If you submit it to Bugguide, crop the photo to just the spider and flower so it will be easier to view as a thumbnail photo. I can crop submitted photos to this site……but I don’t. 🙂
