Staphylinidae: Omaliinae
On the picture with the cone, there is a second, smaller species in the center.
If the images will allow for further ID, is doubtful, but they are worth storing nontheless, showing a biology unusual within the family.

mixed Omaliinae!
The larger ones are either Pelecomalium or Amphichroum (both Anthophagini), I can't be sure from the photos. The smaller yellowish ones on the inflorescence are Eusphalerum (Eusphalerini). Members of all three genera are pollen-feeders.

Thank you! I thought the smal
Thank you! I thought the smaller ones were immatures. I'll try to get down to where I found them, and see if I can get better photos.

Description of beetle
I hadn't realized that these were unknown to me until I looked at the photos, or I would have taken better close-ups.

The beetle has a kind of "jacket" around the shoulders; each half of this has a thin black line down the centre (neck to waist) and a big black spot centered on that line. Otherwise, in the light, the jacket is a yellow-brown.

The tail end is black, with cross-wise ridges or rings.

They were on most of the flowering skunk cabbages, but not on the unripe ones.
