The third photo is of a P test turning from yellow to orange.
Brachypalpus subgenus Crioprora http://bugguide.net/node/view/760623
Looks like a goldenrod (Solidago sp), but I'm not 100% sure.
Clumps look somewhat like CA fescue, but inflorescence does not?
I think this is a raven... or might it be a crow?
Note rounded lobes at base of leaf, not pointed.
Grassland, bottom of Moving Mountain Trail
S. chilense or S. subspicatum
Shrubby lupine, not sure which particular species.
Probably P. elegans, but can't be certain without fresh flowers.
Another female specimen, photographed up close.
Female specimen from a distance.
Lots of this in park trees.
