Description

"The most beautiful crab spider in California" according to Robert Z. Schick, author of 1965 "The Crab Spiders of California".

At the time of writing in 1965, this was called Diaea pictilis...a species described in 1896 and considered native to coastal California from Sonoma & Napa counties south to San Diego and into northern Baja California.

Only later was it synonymized with D. livens...a species of central & southern Europe and reaching east to Iran. Presuming that synonymy is sound, it suggests this may be an introduced species in CA.

For more details on the ID here (with lots of supporting links & references) see this companion BugGuide post.

We watched a roadrunner stalk and kill a mourning dove. See subsequent photos. The roadrunner repeatedly thrashed the bird against the ground. The roadrunner walked off some distance after killing the dove. Great-tailed grackles kept a respectful distance and the roadrunner rushed at one or more when they approached the expired dove. We returned hours later and the carcass was still in place. If I hadn't seen this myself, I would have thought for sure a Cooper's Hawk was responsible and perhaps got scared off the carcass. @karakaxa @noahgaines @featherenthusiast
