larvae

Also just saw the larvae photos. Did the pupating larvae spin a "cocoon" of frass? If so, I have observed the larvae of P. oregonense do this.

no cocoon

There was no cocoon. They just sort of curled up and pupated on top of or under fungal hyphae and frass -- there wasn't anywhere else to do it, but they didn't seem to make use of the frass other than happening to be in the same container with it.

Thanks for the Platydema id!

Platydema

Sure is a Platydema. Probably either americanum or oregonense.

gestalt more consistent with americanum, no?

Diaperine teneb

Diaperinae

Thanks Jim -- that looks pretty good to me. Looks very much like Tom's Platydema photos but I'm not sure what other genera are in California.
