This one had a dark green metallic sheen.
Convinced it is a Heterosilpha, but can't distinguish whether it is H. ramosa or H. aenescens with just this photo as a record.
This flower looks just like one of those in the clusters I'm familiar with in Brodiaeas. I have never seen a single blossom like this so close to the ground.
Widespread throughout grassland.
It was good to see a fair amount of this grass in Moore Creek Preserve. Looking at patches of it from a distance, the purple really stood out from the surrounding green.
Growing in footpath. Formerly called Orthocarpus pusillus.
Alas, my photos are so bad I don't expect anyone will be able to ID this beetle found in a California Poppy. I've read that prior to the introduction of honey bees, Eschscholzia were predominantly pollinated by beetles. This pollen covered insect looked like he was ready to do just that.
I'm not sure what species this one is.
These are in the family Chrysomelidae.
I can report that here are at least three species of Hordeums growing in Moore Creek Preserve thanks to Steve Gerow's assistance. Two are introduced species, and one a native. They are, from top to bottom: H. murinum, H. marinum and Hordeum brachyantherum.
Smaller than the similar Farmer's Barley, Hordeum murinum. In my older books Mediterranean Barley, H. marinum seems to have been H. hystrix.
