Beautiful spider found (by Kathryn) on stem of a tall, lanky, airy coyote brush (
Baccharis pilularis). Habitat was a sunny opening in mixed redwood/oak/madrone coastal forest.
At this point I'm too much of a novice with spider taxonomy to have any ideas on the family/genus ID for this beauty...but I trust BugGuide brethren and/or others will be able to provide guidance ;-)
