Description

This bobcat was about 20 ft. in front of me on the trail. When it saw me, it climbed the fence into a horse enclosure (the horses couldn't care less). Two little birds were watching it fearlessly as it climbed the fence. I think the bobcat might've been after some turkeys who were making a fuss. It sauntered through the horse enclosure, not in a hurry at all. Then it climbed another fence and disappeared into the tall grass. So cool to see a bobcat this close!

Note: unfortunately, some of these pictures were taken through tall grass/weeds, so they didn't turn out as well as the ones with the vivid blue sky as background.

I'm figuring that this is G. baccharisella and not Rhopalomyia californica, mostly because of the lack of lobes in the gall. But I thought I'd see if anyone else has other thoughts on the observation.

On Engelmann oak in Santa Barbara botanic garden. Unlike a blister gall, there is a well defined, somewhat lumpy, mostly flat abaxial organism associated with each adaxial pimple. But unlike the plate gall that white oaks host, these don't seem detachable, plus with Andricus pattersonae there's no adaxial deformation (as there is here in this observation), just downstream damage. And this is well out of range. Last photo is probably of something completely different using the same space, but who knows?!
